This is a complete guide on fixing DNS Server isn’t Responding error.

I was just about to post an article on a different topic, but then I noticed that for some reasons, some websites were not opening up. There were no error messages and the web page comes with an option to click on diagnostic tools to find the cause. I confirmed that my internet connection is working fine as I was able to go to google and look for search results. The next step  was to open these website with browsers such as IE, Firefox and Chrome. The logic is to check if it as a browser related problem. All my web browsers had the same issue which confirmed, this is not a browser problem. Then I tried the diagnostic tool link that popped up in the webpage, which showed me  DNS Server Not Responding Error. After performing some troubleshooting, I was able to fix the issue. Thought I would share it in this article.

Reasons for getting DNS Server Not Responding Error

  • The server which host the website might be temporarily down due to technical reasons
  • The DNS service in your computer is corrupted or not working
  • The security firewall or security software itself might have accidentally blocked your PC from communicating with a website or certain websites

How to narrow down the source of DNS server not Responding Error?

  • If you have another computer or mobile device accessing internet from the same network, then check if they are able to access internet. The other mobile device can be a smart phone or tablet. If the other devices have internet connection, then this is an issue with your computer. If the other devices are not able to access internet, don’t waste any time and contact your ISP. Explain them the scenario and they will help. (Some ISP technicians are quick to blame your computer for this issue)
  • Try to access internet using safe mode with networking. It is explained below under the section “How to fix DNS Server Not Responding Error because of a corrupted security”. If your computer is able to access internet in safe mode with networking, a security software or conflicting third party software might be responsible for the problem.
  • If you are getting DNS server error only on couple of websites, then it might be a temporary issue with the server which is hosting that website. You can check it using websites like http://downorisitjustme.com. Just enter the name of the website that you would like to check. This website will ping to your destination website and let you know if it is up or down. In case if it shows that the website you want is up and running properly, but you are not able to see it, then the problem is with your computer. If the website is shown as down or not working, you need to wait until the webmaster of the website get the issue fixed.
  • Check if the error is a browser problem by browsing websites using different browsers such as IE, Firefox, Chrome, Safari or Opera. This happens rarely, but yet possible. If the error is happening only on a particular browser, then you need to troubleshoot the browser. Following the steps mentioned in IE optimization which fix most issues, no matter which browser you use. Here is how to do a complete Internet explorer optimization.


How to fix a DNS Server Not Responding Error Normally

If you haven’t done any troubleshooting yet, try the steps in this order.

  1. Reset IP and Winsock

The problem might be as a result of corrupted IP and Winsock. Follow the commands in the order to reset the settings.

  • Open command prompt with Admin privilege.
    (For Win 10, right click on Start button > click Command Prompt (Admin))
    (For Win 7 and Win 8, click Start > type cmd inside search window > right click on the result which show command prompt > click Run as administrator)
  • Use the commands in following order
    ipconfig /flushdns
    ipconfig /registerdns
    netsh int ip reset c:\resetlog.txt
    netsh winsock reset
  • Restart computer and check if the problem is fixed.

commands to fix dns server not responding
Note: Flushdns command is used to flush the DNS database cache, while IP and Winsock command reset these settings.

Restart computer and check if the problem is fixed. If not, follow the next step.

  1. Do a Power cycle

Sometimes the problem might be as simple as shutting down and turning on modem/ router. Small changes in computer settings or a change in configuration with router or modem settings may result in DNS error. Once the device is restarted most of these changed settings will be cleared. So follow the step.

  • Shut down your computer and also modem/router for a minute or two.
    Note: It is recommended to turn devices for a minute or two to allow these devices to drain the electrical charge completely which result in a complete reset.

Restart both computer and router to check if the DNS problem is fixed. If not, follow the next step.

  1. Use Global DNS

Replace the DNS server address from ISP with a Global DNS. Global DNS is provided by different private and non-profit organizations. Each server address comes with its own special features which is listed below.

  • Press Windows Key + R. In the Run window, type ncpa.cpl. This will open network connections
  • right click local area connection, then click properties. (If it is wireless connection, right click on Wireless Network Connection)
  • Select Internet protocol version(TCP/IPv4), then click properties
  • Select internet protocol, select use the following DNS server address
  • change DNS server address to global DNS value given below
  • Preferred 208.67.222.222
  • Alternate 208.67.220.220 (You can also use Google’s DNS address preferred 8.8.8.8 and alternate 8.8.4.4)
    change network settings to fix dns server not responding error

Check if the problem is fixed. Changing the Preferred and Alternate error usually fix most of the cases.

Here is a list of DNS addresses which can be used on your computer. You will find the Preferred and Alternate DNS addresses with the provider listed in bold.

  • 8.8.8.8 and 8.8.4.4Google DNS gives faster performance.
  • 156.154.70.1 and 156.154.71.1Neustar’s DNS is safe and fast.
  • 8.26.56.26 and 8.20.247.20Comodo’s DNS for extra security
  • 199.85.126.10 and 199.85.127.10Norton Connect Safe detects pornographic and harmful websites. Ideal for setting on minor’s computer
  • 37.235.1.174 and 37.235.1.177Free DNS Access to all domains irrespective of regional and censorship issues
  • 84.200.69.80 and 84.200.70.40DNS Watch is ideal for high performance.

How to fix a DNS Server Not Responding Error because of a corrupted security

Security software is another major culprit responsible for DNS Server Not Responding error. Every security software tends to get corrupted over a period of time for reasons ranging from file corruption while updating files, conflicts with other software or indirect changes to security settings as a result of intentional or unintentional changes made on your PC. This might cause the security software to block internet connection.

  1. Configure Security Software properly

It is possible that your security software may have got corrupted or not working properly for variety of reasons. Check if your security software is configured properly especially the Firewall settings.

  • A good method to check this is disable all security software and firewall. Then check if the problem is fixed.
  • If not fixed, try one more time by resetting all security software and firewall settings to default. Check the status.
  1. Check the internet status in Safe Mode with Networking

Safe mode is a troubleshooting mode that allows only the essential operating system files and drivers to load. All third-party software’s and drivers are prevented from loading. When you select Safe Mode with Networking, apart from the basic OS files and drivers, network driver is also loaded so that you can go online. Once you reach the desktop, try to go online. If the internet works fine, a third-party program installed in your device is responsible for the problem.

The logic behind using Safe Mode with Networking – If the internet connection works fine in Safe Mode with Networking, then it should be the third-party services or driver which is responsible for the problem because these are the services which are blocked in Safe Mode with Networking.

The major culprits to look for in third party services

  • Disable or remove security software
  • Uninstall any recently installed device driver
  • Uninstall any recently installed software


DNS server not responding showing only for some websites

Sometimes the error message happens to only some websites. Of course, you can check if the website in question is working using www.downforeveryoneorjustme.com or http://downorisitjustme.com. But what if this is happening on authority websites like Google, Microsoft or Yahoo. You cannot expect these websites to be down and it happens very rarely. The solution mentioned below is simple and it worked very well for me. I apologize for not having any logical explanation to why this error happens only to some websites. You are always welcome to share your opinion on this.

  • Open ncpa.cpl from Start tab. Open network connections
  • Right click local area connection, then click properties
  • Select Internet protocol version(TCP/IPv4), then click properties
  • Select internet protocol ,select “use the following DNS server address”
  • change DNS server address to global DNS value given below
    Preferred DNS Sever 208.67.222.222
    Alternate DNS Server 208.67.220.220

Providing the global DNS should fix the issue. In some cases, this solution might be temporary as the error message might return after a week or month (This happened to me). The trick now, is to remove the global DNS and go back to select “obtain DNS server address automatically”. Then if it happens again, change it to global DNS. Switching between alternate DNS server address and automatic DNS server should fix the problem.

Other solutions to try for DNS Server Not Responding (If above mentioned methods fail)

  1. This solution works for wireless connection issues
  • Start -> control panel -> network and sharing center
  • change adapter settings on the left side
  • disable Microsoft Virtual WiFi Miniport Adapter, if present.

If Microsoft Virtual WiFi Miniport Adapter is not present in the location, go to device manager and disable it.

  • Start -> Run ->Type devmgmt.msc ->Click View tab
  • Select Show Hidden devices ->Expand Network Adapters
  • Disable Microsoft Virtual WiFi Miniport Adapter, if present
  • Check the status
  1. Disable Internet Protocol Version 6

Start -> Run -> Type ncpa.cpl -> Right click Local Area Connection or your current connection ->Select Properties -> Uncheck Internet Protocol Version. Restart computer and check the status.
ncpa.cpl

  1. System Restore

System restore feature enable you to restore your computer to a previous date and time when the computer was working fine. I rarely recommend system restore as a solution because most of the time system restore just mask the real problem and give a temporary solution. But considering the fact that you tried all the above steps and none fixed the problem, try doing a system restore to a date when the internet was working fine in your computer.

Try doing a system restore as mentioned in the link.

If none of this worked, contact your ISP to get further help in fixing the problem.

    Thanks Anup. I think I have solved my long pending problem(s).

  • Danny Jul 15, 2017, 6:19 pm

    hi anup, I’m danny frm kerala, i red ur article , i am having the same DNS server issue, but am little confused here, i am using Reliance ISP at my home, for the past few months am getting this dns server error and its so frustrating too, so i want to know if this is my computer issue or the issue from the main ISP. I cant login in my laptop and in my mobile and also in my desktop.Every where the net is disconnected. I have put down a complaint with my ISP and fr few days net was fine then again this same DNS error popped up, I am not able to get a steady network, oneday net is fine then for another few days its totally gone, so i just want to know if this an error issue from the main ISP or does my home network having any problem. Do i need to configure the router / modem or should i have to go through the steps u have mentioned in ur article. In ur article u have said, if the network error is showing in all my devices such as laptop, mobile and desktop then i have to get in touch with my ISP. So is my issue related to the main ISP or will there be any use if i do the following steps or configure my modem ?. Would really appreciate ur kind reply and i really hope u could help me out.
    Thank you,
    Danny.

    • Anup Raman Jul 17, 2017, 2:15 pm

      My sincere apologies for replying late by a day.

      This clearly is a problem with ISP. Remember the problem is happening in your laptop, desktop and mobile at the same time. Since all these machines have problem at same time, this points out a problem with modem cum router. You need to bug your ISP until the problem get fixed.

      Changing your DNS address to google DNS is a solution that you can try for the time being.

      Let me know if you got further enquiries.

      • Danny Jul 20, 2017, 12:08 pm

        hey anup, thank you for ur kind reply, yes it was an issue with the ISP , there was some problem with there cabel and they repaired it, it took a week for them to repair it lol, now it’s working as normal. thank you so much for ur time. Really appreciate the help u do out here, Once again thank u for ur reply. Have a grt day , tc .

    Waiting for help

    • Anup Raman Jun 24, 2017, 5:48 am

      Shutdown your modem cum router,wait 2 minutes for recycling. Turn off your tablet. Turn on router/modem. Then turn on tablet. Now check if the internet connection is back.

      Do you have internet connection in other devices which is connected to the same network? Check and let me know the results.

    Lenovo Flex 3-1580 80r4, Intel Dual Band Wireless AC1365 card, Windows 10

    Moved to new city last week, DNS not responding problem occurring constantly- periods of internet access, but interruptions fairly often. It DID happened in prior city, but only once a day at most, and power cycle of wireless router or computer reset fixed immediately. Here, problem persists-

    Have done the following, with no fix lasting longer than few hours at most, still constant error that disconnects internet for a while-
    -Updated drivers (and windows), problem occurred prior to update, still occurs post
    -Kaspersky uninstalled, ran computer on just native windows defender (clean wipe of kaspersky using ccleaner best I could), error still occurs, reinstalled latest kaspersky, still same problem
    -Flushed DNS, changed to every single alternate DNS server
    -Connected via ethernet cable
    -disabled Microsoft Wifi Direct Virtual Adapter (named differently than the option listed in the post, don’t know if it is the same), no luck
    -IPV6 disable, same result
    -Attempted SafeMode Networking, was unable to establish a wireless internet connection, NOR an ethernet one- this is a problem I’ve seen listed in other forums- windows 10 apparently makes this VERY hard (if not impossible) to do for wireless at least. I have tried the workarounds that people mention- ctrl/alt/del and the “lock” screen pre-login (I cannot even access task manager when I do this, perhaps it has something to do with auto logged account? I have only one account listed on this computer, and have not setup a microsoft account), and have no access to “available networks” as the adapters apparently are not loaded with safemode networking (which again, seems strange, but again, this is something that has been mentioned on other sites and tech forums). One reason listed in those other posts/forums is that perhaps it’s the type of wireless card and/or settings on it, but that seems unlikely again as the drivers seem completely disabled in safemode/networking.
    – I also ran SFC file checker as admin under cmd, no corrupted files found, BUT it did seem to allow the internet to run smoothly…for a day…after which I am back to my current situation. I do not know if this is a possible reason or not- and does not seem viable as a constant fix needing to be applied.

    Other computers and my phones can all access the internet, no problem, no errors, and no random DNS servers popping up at random.

    Other ideas I have yet to try-
    -configuring the wireless cards settings differently? I do not know what would/should be changed, but the options are very varied for the wireless card under the network properties options.
    -Update Bios (I’d like to avoid this as my computer is still under warranty)
    -Static IP setup thru the router
    -Flashing the router firmware? (unlikely, as again, seems isolated to my computer, and router is ISP provided so this is just me grasping at straws)
    -I will try to see if there are any other software issues- I have not installed any new software since moving, and my computer is already fairly bareboned as is- I uninstalled all the bloatware I could, tho perhaps the native Lenovo System Interface software is causing this issue – I uninstalled it and am unable to re-install it since. Again, I am looking at any possible options or reasons.
    -buying/installing a new wireless card?

    I’m am going on one week of frustration at this point, having tried everything I can think of, and nothing as far as the last few options I listed. If anyone could offer insight or assistance, it would be a greatly appreciated lifeline as this has been a constant disruption in my life. Thanks again.

    • Anup Raman May 25, 2017, 2:17 pm

      Strange….You tried almost everything that I can recommend. Just couple of suggestions here.
      1) can you try this command in command prompt with administrator privilege. This command only works with admin rights.
      netsh winsock reset
      2) Disable or reset security software to default settings.
      Hope this might help.

  • Cosmin Marian Jul 23, 2016, 7:09 am

    Alright,I did all the stuff You said right there,i changed the dns adresses,i rebooted the router,i flushed de dns cache,i had reseted the ip and the winsock,i restarded the PC and it’s still not working,I had been waited 2 days because i tought it was a problem with the servers but it wasn’t.What should I do?

    • Anup Raman Jul 23, 2016, 7:22 am

      If all the steps in this article is followed, there is nothing much you can do differently other than getting help from ISP.

      On the other hand, here are somethings I want to cross check.

      • Do you have other PC’s or cellphones using the same internet connection? If those devices works fine, the problem is narrowed down to a problem with PC. In the other case, internet connection is the problem which might be the ISP itself or internet settings
      • Did you restart computer in Safe Mode with networking? If the internet works fine, a third party program is blocking internet connection.
      • Did you disable security software? Did you disable firewall and check if that makes the internet work. If so, there is a problem with security software. Either configure it properly or re-install the software properly.

      Please check and let me know the status.

  • Michael Jul 13, 2016, 7:24 pm

    My internet stopped working yesterday. I called WOW today and they tried resetting my modem a few times. That did not fix the issue. I own my modem so they told me they could not help me any further. I was getting a DNS server error. I tried a couple of your solutions but changing the DNS address to global seems to be the one that fixed my issue. I have internet again. Thanks!

  • Ayush Shekhar Jul 3, 2016, 12:06 am

    Thanks a ton for your support and effort… this post helped me fix the issue… Kudos to atechjourney!

  • jen Apr 17, 2016, 2:13 pm

    Your comment about starting in Safe Mode with internet – that was the key to diagnosis. A DNS server not responding that was caused by Norton 360 being ‘damaged’ and requiring a reinstall. I have wrongly been looking at the DNS as being the culprit. Your advice provided the insight I needed and solved this long standing problem. Thank you.

  • Shari Jan 21, 2016, 9:42 pm

    Thank you! Changing to global DNS worked for me. I appreciate you sharing your knowledge.

  • Mac Oct 7, 2015, 11:16 pm

    It was the Firewall,in my case. This was requesting to update, but as DNS server was not working , could not update. Hence an “infinite loop”. So, uninstalling and rebooting enabled the computer to connect without inteference by the security software.
    Many thanks for this help.

  • Michael Sep 15, 2015, 2:42 pm

    Brilliant! Two days of headache trying to sort out why the Adobe Download server would not respond in Windows 10. Discussions with Adobe tech and no joy. Then a complete fresh install of windows 10, only to see the same error in my Adobe Lightroom 6CC program. Congratulations, I put in your manual DNS settings in my Local Connection and it downloaded the Adobe updates without fault.

    Thank you so much for sharing your knowledge.

  • Steph Sep 3, 2015, 5:13 pm

    I found out it was my Bitdefender’s firewall. searched and found the correct settings the wireless adapter had to have and now it’s working. Thanks!

  • Jaskirat Aug 17, 2015, 6:41 am

    Hi anup, im a win 7 user … I use internet on my pc through network over bluetooth,earlier it was working fine but now it shows a yellow warning mark on internet icon on the taskbar when i troubleshoot it says your dns is not configured properly/not responding plz tell how can i fix this problem?

    • Anup Raman Aug 18, 2015, 5:12 am

      1) Right click Computer -> Manage -> Device Manager
      Under Network Adapters. Check if bluetooth is enabled and drivers are installed properly. If there is a yellow exclamation, there is problem with Bluetooth driver. Uninstall and re-installing the driver should fix the issue.
      If there are any other Bluetooth entries listed there, make sure it is enabled and the drivers are installed properly.

      2) If Bluetooth is working fine under Device Manager and the issue is still not solved, right click on the yellow warning on internet icon.
      Click Troubleshoot Problems. This initiate a network diagnostic scan. If you reach a point where it asks to reset network adapter, select the option for resetting all adapters.

      3) If none of the methods worked, disable or remove security software which might help fixing the problem.

      Please update the results

  • BRENDOW Aug 16, 2015, 3:48 pm

    Hi,

    I upgraded my new desktop to Windows 10 one week ago, upgrade went well and since the upgrade. After about half an hour of use I am getting a “DNS Server isn’t responding” message for every router I try to connect to. I have done the usual DNS fault resolution items:

    1 – Manually entered a DNS
    2 – Checked Router settings
    3 – Restarted the Router
    4 – Flushed DNS, wi
    5 – Used other computers to connect to the router (Laptop PCs running 8.1 and 7, Samsung Galaxy S5 x2, IPod and Iphone 5) which all connet fine
    6 – Connected to different routers

    I am at a loss of how to resolve this issue.

    • Anup Raman Aug 18, 2015, 5:26 am

      1) Right click on the yellow icon on the network status icon on the taskbar. Click Troubleshoot Problems. This action initiates a network diagnostic scan. If it asks to reset network adapter, select the option for resetting all adapters.

      2) Disable or uninstall the security software and check if the problem is solved.

      Hope this helps.

    Hey, thanks. Solved the problem AVAST left me in !

  • Storme Aug 8, 2015, 7:05 pm

    It’s my bit defender how do I fix it I’m re installing it now but if it doesn’t help what should I do?

    • Anup Raman Aug 10, 2015, 12:40 pm

      Usually, If it is a security software problem, uninstall and re-installing it should fix the issue. But if for some reason it doesnt work, there might be a problem with basic software settings. You need to make sure the software is removed properly without leaving any trace of files or settings associated with the software.
      In this case, use Bit Defender uninstall tool from the link

    changing DNS server address to global DNS value helped me.
    Thank you so much….

  • Wxo Jul 13, 2015, 11:44 am

    Changing the DNS did it for me. Thank you!

  • Solomon Botchway Jul 6, 2015, 10:40 am

    Well the best solution, is to use the Google DNS 8.8.8.8 and 8.8.4.4.
    It solves the issue best.
    You may need to flush the dns in cmd .

  • Kaushik Jun 5, 2015, 3:05 pm

  • Berry May 26, 2015, 10:25 pm

    pls help.. I’ve tried everything stated above but it didn’t solve my problem. I tried changing that preferred/alternate dns servers but still nothing changed. i even tried that ipconfig/flushdns and even that restore system. it also didn’t work in safe mode. the internet connection exists but i can’t access any website like google and youtube. when i try to troubleshoot, it said that the dns isn’t responding. this has been happening for a few months now. do u know anything that can help me fix this?

    • Anup Raman May 31, 2015, 3:01 pm

  • Giorgio Apr 5, 2015, 4:02 pm

    Hi Anup,
    I moved to China and I’m having problems with Internet connection. We have a new WiFi at home. My friend has a chinese computer and can connect. My PC is not chinese and I can’t Connec. Until 2 weeks ago I was living in Honk Kong and no problem. The problem is server dns doesn’t respond. What’s weird is that sometimes, but very rarely, don’t know why, it does connect but after 5-10 minutes it disconnect Again. I thought it could be my PC or some settings but if I use it in my office I can connect. Then it might be our home network but again my friend’s PC no problem and my mobile too can access. So I’m going crazy trying to understand whether it’s my PC or else? I tried to disable windows firewall and Kaspersky firewall. Same result, server doesn’t respond. Should I myb change some protocol since I’m in China and elsewhere I never had connection problems? Please help me. Should I bring my PC down to some store and have it reset?
    Thanks a lot
    Giorgio

    • Anup Raman Apr 7, 2015, 2:23 pm

      Hi Giorgio,

      Your laptop is working fine. That is evident from the fact, it can get connected at your office and other locations without problem.

      Whenever there is an issue with connectivity related to different geographical location, the culprit had to be the security software. Instead of disabling Kaspersky, uninstall and then check if the problem is resolved. Make sure to back up Kaspersky product key, so you will be able to re-install it after the problem is fixed. Also reset windows firewall to default settings and then try to connect.

      If the above method failed, this has to be a problem with software conflicts. Check the list of installed softwares. Remove if there are any unwanted softwares especially security softwares which is not used anymore or trial versions.

      Resetting the PC might help, but I can only recommend it after all the steps are exhausted. I would rather prefer you to try the recommended steps and let me know the status before trying PC reset.

  • enzo Mar 31, 2015, 5:16 pm

    Hey man. I have a problem with my other gadgets because it connects to the router but it has no internet connection so I thought the problem is in the computer so I checd it and found the DNS server problem then I fixed it by your amazing steps but still my other gadgets like my iPad, iPod and Acer adriod phone has no internet connection while my other gadgets have internet connection please help me , and thank you for that great info. I fixed my PC. DNS server problem with that

    • Anup Raman Apr 1, 2015, 6:25 am

      Thanks Enzo for the feedback. Try these steps.

      In your iPad and iPod, try this.

      1. Go to Launch Settings App
      2. Tap on the Wi-Fi that you originally connect to
      3. Tap on Forget this network
      4. Tap on Forget button
      5. Restart your Device
      6. Go back to list of Wi-Fi networks available
      7. Connect to your Wi-Fi

      Check if it is able to connect now.

      On your Acer Android Phone, try this

      1. Go to Settings and connect to Wi-Fi
      2. Tap on your Wi-Fi that you are connected to
      3. Click on Forget Netwrok
      4. Reboot the phone and check if the Wi-Fi is working

      I recommended these steps hoping that, by trying the troubleshooting steps mentioned in this article, your Wi-Fi settings might have reset completely. This may not be updated on these devices. By re-establishing the connection here, I hope the device will update the new settings and fix the problem.

      Please update on the results. And let us know more details, if the problem is still there.

  • Cynthia S Mar 24, 2015, 4:12 pm

    Hi, that information is really great but do you have anything on first gen. IPAD 5.0?
    I have wi-FI home and I also have a MacBook Pro and this IPad along with my own router/modem . My problem is my MacBook Pro works find with the internet but sitting next to it I am trying to use my IPad but it has a problem not connecting to the Internet (get this, it works fine at other places). What gives? HELP thanks very much for all your time and trouble.
    Cynthia

    • Anup Raman Mar 24, 2015, 5:40 pm

      Hi Cynthia,

      This tutorial is meant for Windows users, so didn’t mention anything about Apple devices.

      However, from whatever you said it seems to be a problem with iPad. Try this.

      1) Try connecting internet from near the router. This is to check, if the distance from router is a problem. If that is the case, you need to keep your iPad updated with latest updates which may improve the device performance(since it is 1st generation iPad, it is a possibility). If both Macbook Pro and iPad don’t get connected after reaching a certain distance from router, the problem must be weak signal. Check this article on How to boost Wi-Fi signal from Router

      2) Create a new profile and check if you are able to connect.

      3) Reset the device. This is to make sure wireless settings are configured to default settings and then try to connect.

      4) Give a call to your ISP. Ask them to check if there is any settings inside router which might be preventing iPad from connecting to internet (I doubt this, but certainly worth trying if none of the above steps worked)

      Glad if you can update us on the result. In future, this will help others with the same problem.

    • Anup Raman Feb 5, 2015, 11:32 pm

      1.Check if the firewall is not accidentally blocking VPN connection. Disable or Reset firewall settings and check if the issue gets fixed.
      2.Check this link http://atechjourney.com/how-to-do-a-complete-internet-explorer-optimization.html/
      Try the instructions in step 7.
      •Check the option Automatically detect settings. If it is already checked, uncheck the option.
      •If that didn’t work, check if Proxy server settings are proper.
      Please update the result.

    Hi, i have a problem with the LAN connection. I can connect using the wifi but everytime i try using the LAN i get this error “DNS server not responding”.
    Looking forward for your answer

    Thank you

    • Anup Raman Jan 30, 2015, 10:03 am

      Hi Peach,
      I wonder if you tried the same steps mentioned here, on Local Area Connection under the list of network connections. Changing the global DNS or google DNS should help. If it is already done, try the option which automatically assign DNS address.
      Reset firewall settings to default and check if it is not accidentally blocking internet connection.
      Feel free to update me on the results.

  • ictiempo Jan 24, 2015, 1:54 am

    Hello Anup,

    You’ve got the best solution on dns problem, however my experience is different. The issue on my PC wasn’t security software but a bandwidth controller which I used to equally distribute the bandwidth on my network. A simple re-install of the software solved the dns problem. more power…..

  • Aashish Jan 22, 2015, 9:51 am

    Thank you for your advices. But i have a unique problem. The DNS server doesnot responds at my home only. The router is all right, and none of the above stated problems i encountered. My laptop is showing this message since i bought it some months back. I use google chrome and for about first 5 minutes it shows no problems and then, DNS SERVER NOT RESPONDING. I will be thankful if you will be able to shut this problem.

    • Anup Raman Jan 22, 2015, 6:30 pm

      If this is my machine, I’ll try the steps in following order.

      1. Go to device manager. Right click and uninstall all entries listed under network adapters. Restart computer. If you are using Win 7 or Win 8, it is almost guaranteed that the drivers get re-installed automatically after restart. Check if the issue is fixed.
      2. Go to firewall settings and change it to default settings to make sure that the software is not accidentally blocking any communication. Restart computer and check if that makes a difference.
      3. Uninstall security software. Also, go through Programs and Feature to check for suspicious looking programs. If you are sure, you don’t need a particular program, remove it. Restart computer and check if the issue is fixed.

      Try this and let me know the results. Good Luck

      right click local area connection, then click properties
      Select Internet protocol version(TCP/IPv4), then click properties

    when i change the dns it stays der and it doesnt change except after 30sec or 1 min it does da ! sign on the network on the taskbar when it says to reset the router i reset it but it still doesnt work but sometimes after 10 minutes it goes back and then after 5 mins it goes away too what is da problem???

    (added it again since it doesnt give me to the comment instead to another one)

    • Anup Raman Oct 28, 2014, 11:21 am

      Are you using Win 8 or 8.1? If yes, uninstall both wired and wireless network adapter. Restart computer. It will automatically install the drivers for the devices. Now check if that fixes the problem.

      • Bruce McKeown Dec 23, 2014, 6:25 pm

        Yes–this works. I searched far and wide for a solution, read through the instructions above and tried them, then read your response and it was the miracle fix. All Win 8/8.1 users need to try this first. Thanks!

  • Vaseem Oct 26, 2014, 10:07 pm

    hi as soon as I change ipv 4 settings the Internet works for 1 min again the DNS problem it shows 127.0.0.1 this is always there if I change again it’s the same.
    I’m using Microsoft essential as antivirus and windows 7 home premium.
    Plz help

    • Anup Raman Oct 27, 2014, 11:55 am

      Something is responsible for changing DNS automatically. Mostly it should be a malware which is causing the problem. Run free software such as superantispyware, avg free edition etc. You don’t have to install both softwares. Just install one, do a scan, remove the infection, then remove the software before installing the other software. Scanning using multiple software is done to ensure the malware which escapes detection from one, might get caught by the other.
      It is also highly recommended to remove unwanted files using the free software Ccleaner.
      Good Luck.

  • Ariel Hanks Sep 1, 2014, 1:51 pm

    I tried the firewall again and reset it. It has no effect at all. I called Comcast and had them turn off the hot spot they broadcast from my router. They did and that had no effect.
    Thanks for the help Anup.

    • Anup Raman Sep 1, 2014, 3:37 pm

      Logically, if the other devices don’t have any problem with internet connection, this should be an issue with Laptop not from Comcast.
      If it is not of much trouble, could you please try uninstalling security software and check the result. At times, if security software is corrupted, even disabling or resetting settings won’t make any changes to the settings. (This suggestions comes from years of experience working for Microsoft and Symantec)

      • Ariel Hanks Sep 1, 2014, 9:54 pm

        I tried disabling and re installing MSE twice. I have updated the wifi card software and drivers. I updated the Bios. I have used googles public dns servers. I am getting auto config errors also. I have no strange 3rd party software only ccleaner, apache office, chrome, last pass, firefox, Nero, Cannon printer software, Adobe, and I uninstalled MBAM. All other software is intel, windows, and HP. The errors/warnings in event viewer are aas follows. The DNS errors are very few now. I have kernel power to processor errors due to firmware still even after bios update. I have istc agent not found or corrupted OEM default registry path does not exist. I updated the Intel smart connect and still have the same isct warnings.
        I still get 60mbs on ehternet and anything from 1mbs to 19 mbs on wifi it is up and down. If I am on The LAN and get 60mbs then it cannot be the firewall on the comcast router router correct?

      • Ariel Hanks Sep 2, 2014, 4:19 am

        I have recently found my same issue on the internet. It seems that the experts believe it has to do with the way Comcast handles Qo’s packets. Other people have the same symptoms of high speeds with Ethernet and safe mode and upload speed is good yet the wifi has problems authenticating most dns. The fixes are just workarounds involving different methods like buying your own router and other things. This phenomenon only happens with a few select wifi systems on select devices. I ant really expand on the fixes as the opinions and outcomes are inconsistent.

        • Ariel Hanks Sep 4, 2014, 12:44 am

          Update: Solution for COMCAST GATEWAY routers. If you are a comcast customer and like me you experience DNS Dhcp and Autoconfig errors and your upload speeds are fine over wifi but the download speeds are slow and inconsistant, yet when in safe mode or hardwired you have no problems. Then do the following. !rst step call tech support at comcast and ask them to guide you to disabling WMM (wireless multimedia messaging) under advanced settings/ QOS/ Wmm. If your router does not have this option then buy your own wifi router and you might as well get a modem and save the monthly fee. I suggest not trying to get them to send you another gateway router that has this “wmm option setting” because the people who give out the routers do not know which ones have it, and you will have to make a trip to their service centers and wait in line. I bought a dual band which is a better wifi router for $60. Then I bought a modem docsis2 for 20 bucks off craigslist. Get a docsis 3 modem if you have 50mbps speeds or more and also have at least 3 people online at one time.

          • Anup Raman Sep 4, 2014, 3:01 pm

            Thanks Ariel for sharing this information and following the thread. I will update this information in highlighted area, so that it will help others with the same problem.
            Thanks again 🙂

  • Ariel Hanks Sep 1, 2014, 3:29 am

    I have an Arris router from comcast. I have Dns errors while on wifi, only with my laptop. In safe mode I get 60mps. Other devices work fine. Ethernet connection gets 60mps in regular mode. My Laptop is fine every where else I try wifi connections. I tried all of your suggestions, I think correctly. No results. I have been on the phone three times with different technicsal people from Comcast. I traded out routers with them I had a technicolor first. They have no Idea what the problem either. I have given up and would love it if you could help. Thanks.

      I suspect the security software installed in your computer. Check firewall. Turn it off and check the result. It’s good to reset the firewall back to default value as it may have accidentally blocked your wi-fi settings.

    I hope your still available for help. And if so thanks so much in advance.

    Hi, So just as of two days ago for some reason my internet (wifi) hasn’t been working properly and sometimes isn’t working at all but it is only happening on my laptop. Every time I do the trouble shoot it comes up with , ‘Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding.’

    I’ve tried doing a system restore to before it happened and that didn’t work. If anyone can help it would be much appreciated.

    -My laptop is a Lenovo Y510P
    -My internet provider is Comcast, and the router is Arris – Model #TG862G/CT.
    -Windows defender is my anti virus.

      Hi Anthony,

      Just a quick look, I don’t see any problem. But I’ll go through the log once again. Please try this. Go to device manager. If you have bluetooth enabled, please disable it. Restart computer and then check the status.
      I wonder if this has something to do with what I experienced as mentioned in this article. http://atechjourney.com/fix-wi-fi-keeps-disconnecting-in-windows-8-and-8-1.html/. Please do update the results.
      Good Luck

        Thanks for the prompt reply, when i click on blue tooth there are three different options,: Intel Centrino Wireless Bluetooth 4.0 + high speed adapter, Microsoft Bluetooth Enumerator, and Microsoft Bluetooth LE Enumerator. Should I disable all three?

        Thanks again,
        Anthony

        • Anup Raman Feb 14, 2014, 8:07 am

          Disable one by one. I think disabling first one automatically disable the other entries. If not, do it manually for all the entries.

        • Anthony Contreras Feb 14, 2014, 8:08 am

          Sorry me again, in the above comment the bluetooth options were just in device manage > bluetooth.

          Should I be looking in device manager > network adapters ?

          Thanks

          • Anup Raman Feb 14, 2014, 8:12 am

            Yes, These entries are to be disabled from device manager. Right click on the entry and disable it.

            • Anthony Contreras Feb 14, 2014, 8:27 am

              K I disabled these from, Device Manage > Bluetooth : Intel Centrino Wireless Bluetooth 4.0 + high speed adapter, Microsoft Bluetooth Enumerator, and Microsoft Bluetooth LE Enumerator. Restarted computer and still unfortunately getting the same issue.

              There is a Qualcomm Atheros gigabit ethernet controller under network adapters, should I disable that too?

              Thanks again,
              Anthony

              • Anup Raman Feb 14, 2014, 9:26 am

                Press Windows Key + R. In Run window, type ncpa.cpl. Right click on wireless connection, click Properties, scroll down and click on Internet Protocol Version 4, then click Properties. Select both Obtain an IP address automatically and obtain DNS server address automatically. Restart and check the result.

      If it works in safe mode with networking, it’s a clear indication that the culprit is a third party software, accidentally blocking internet connection. Usually in this case, it is the security software.First step is to disable security software and then check if it is fixed. If not, uninstall and then check if you can go online.

      • ARU Feb 12, 2014, 4:24 am

        what do you mean by “third party software, ” here????? is this any anti virus protection software???

        • Anup Raman Feb 12, 2014, 5:21 am

          Any software which is not part of windows operating system is considered “third party software”. Usually, in a case like this, security software is the major culprit for creating such issues (from my experience) due to file corruption or accidental changes in settings. So first, disable it and check if the issue is fixed. If yes, configure the security software properly, so it won’t block your internet connection. In some cases, even disabling the software may not fix the issue, if the software is corrupted. So try uninstalling it and check if that fix the issue.Once the problems are fixed, you can install the security software back.

          • ARU Feb 12, 2014, 5:56 am

            can you please explain the procedure 4 this..plz?

          • ARU Feb 12, 2014, 5:58 am

            recently s/m displays a message that “mindspark toolbar platforms stops monitoring” is this message related to this issue??? if yes what i have 2 do 4 this…plz help me?

            • Anup Raman Feb 12, 2014, 6:38 am

              Press Window Key + R.This will open Run window. Type appwiz.cpl. This will open a window which lists all software’s installed in your computer. Click on the security software that you want to uninstall, then click on Uninstall. Also remove if you “mindspark toolbar” listed.

              • ARU Feb 17, 2014, 12:14 pm

  • dMONK Dec 2, 2013, 5:00 am

    Hey! I wanted to ask will this work for dynamic ip connection?? I’m using reliance broadband connection and Dlink dsl 2750u. Whenever I call em for help they ask me whether it’s working with the modem they provided?! I tell em that it works with that modem. So they say they can’t help with my new modem, n I need to call some technician.

    • Anup Raman Dec 2, 2013, 10:25 am

      Yes, these methods work for dynamic ip address. This is what I learned from experience. ISP technicians just quickly try out one or two method and if it didnt work, they are quick to blame these issues on OS or other faults.
      Follow the methods mentioned here. There is not one or two, but multiple methods mentioned clearly. Hopefully, one of this step will get the issue fixed.

  • rob g.-L Dec 2, 2013, 12:56 am

    While traveling in Illinois, you’ll find rest stops over the highway called oases; they’ve got free WiFi and can be troublesome at times. This article helped me solve my connectivity issue, simply by adjusting the DNS address(es) to Google’s preferred numbers. Well written walkthrough, imo. Keep up the good work, thanks!

    Changing the dns to 208.67.222.222 fixed the problem on my desktop, but I can’t use my laptop because I cannot connect to wifi

    • Anup Raman Nov 9, 2013, 2:27 pm

      Nick,
      Not sure if your desktop is also connected wirelessly or directly connected using cable.
      Try the steps.
      • Try the same steps that you tried in desktop on laptop
      • Do a power cycle as mentioned in the article.
      • Check if the firewall is not accidentally blocking internet on your laptop.
      • Check if the network adapter is working fine. If possible, re-install it
      • Run the command netsh winsock reset
      Good Luck. Let me know the results.

  • lui san Nov 6, 2013, 8:06 pm

    Amazing! Worked perfectly! Thank you so much!

    Thanks for the help…….tried everything …them oh its the friggin firewall..all good now.

  • Alphonse Nov 4, 2013, 5:47 pm

    Mr. Anup
    I have the same dns problem, I have tried all the mentioned ways and it’s still not working, other devices can connect but no internet access, its still doesn’t work at safe mode and I already used system restore, but alas the yellow mark remained 🙁 please help me sir.

    • Anup Raman Nov 5, 2013, 6:15 am

      Hi Alponse,

      Since the other devices are working fine, there is no issue with internet connection. The problem is with your computer.
      Could you please try uninstalling the network driver, then re-install it and check if that fix the problem.
      If not, Let me know which operating system is installed in your computer.
      Good Luck

      • Alphonse Nov 5, 2013, 3:51 pm

        Mr Anup,

        After I uninstalled and installing the network driver I still got the same result 🙁 , and other devices cannot connect to the internet, but they are connected to the router, it’s windows 7 professional sir.

        • Anup Raman Nov 5, 2013, 4:43 pm

          Apologize for getting the details wrong.Now the scenario is entirely changed. Your router is working fine since all the devices are connecting to network, but no internet. This is clearly an issue from the modem.

          • Hopefully, you did a power cycle of modem. Turn off the modem router, make sure there is no power supply for 5minutes. This is to allow excess charge to drain off. Turn on the modem and router in that order.Check if the issue is fixed.
          • Click Start -> Run ->ncpa.cpl -> right click on wireless connection -> Properties -> Select Internet protocol version(TCP/IPv4) -> click properties -> select “use the following DNS server address” -> change DNS server address to global DNS value Preferred 8.8.8.8 and alternate as 8.8.4.4. Click Apply and click OK. Restart computer and check if the issue is fixed.
          • If still there is problem, you need to contact your ISP. They will be able to fix it quickly after resetting modem settings.

          Good Luck Alphonse. Feel free to inform me the results.

          • Alphonse Nov 5, 2013, 6:22 pm

            Mr Anup,

            I have done all the procedures mentioned there just now, still no internet access, the only choice I have is to contact my isp I suppose, thank you for the replies mr Aman, I really appreciate it, keep ip the good work!

            Regards

            • Anup Raman Nov 6, 2013, 2:41 am

              Hi Alphonse,

              Thanks for the feedback. Please do contact ISP and let us know the results. This can be a learning to all of us.

          Hi Chantal,
          Disappointed to see the issue is still not fixed. Could you please try this in this order?

          • Do a system restore. Restore your computer to a point where the internet connection was working fine.
          • If it didn’t work, remove your security software especially the one with firewall in it. Check if that fix the problem.

          Wish you good luck buddy.

    Anup,

    After struggling with a very frustrating (CANNOT COMMUNICATE WITH PRIMARY DNS SERVER ERROR) on my desktop computer for over two weeks, I was able to find the solution here on your website with my laptop. I searched for a solution on other websites but nobody seemed to know how to fix the problem. Changing the Preferred and Alternate DNS address to 8.8.8.8 and 8.8.4.4 fixed the problem. Thank you very much

  • kenneth Jun 28, 2013, 11:23 am

I was on the verge of taking my computer to a shop and paying to have it looked at :/ You saved me time and money, and gave me the confidence to look into fixing these problems myself in the future!

      Hi Kenneth,

      Thanks for keeping faith in me.Whatever that can be done on a DNS issue is explained here and there is not much I can do if the issue is still there.

      In this case, I see there is no alternate DNS server address mentioned.

      Try this
      Change the primary DNS address to 8.8.8.8 and alternate DNS address to 8.8.4.4. Now restart the computer and check if the internet is working.

      If not,
      1)Open ncpa.cpl from Start tab. This will open network connections
      2)right click local area connection (If it is a wireless connection then click it), then click properties
      3)Select Internet protocol version(TCP/IPv4), then click properties
      4)Select internet protocol, select obtain an IP address automatically.
      5)Close the window, restart and check the status

      Hope this fix the problem. Please let me know the status.

      Good Luck

        Thank you so much! I guess my laptop needs a day before try to log on again
        I’m hoping that this will be the end of my problem LOL
        your a life saver thank you so much 🙂

        the problem back again…. 🙁
        I guess the problem happened when I locked my computer for a while (I usually lock it to avoid my cousin used my computer)
        Is there any connection to my wild guess? I can’t access now some websites again.

        • Anup Raman Jun 23, 2013, 3:09 pm

          Kenneth….send me the result for ipconfig/all log. Need to take a look.

            • Anup Raman Jun 24, 2013, 1:41 pm

              You have not made the changes that I suggested before. The DNS server still shows 192.168.1.1 and there is no alternate DNS mentioned in the log. Please do it and let me know the result.

              • Kenneth Jun 25, 2013, 10:42 am

                I’ve tried to change DNS address to 8.8.8.8 and alternate DNS address to 8.8.4.4. but it doesn’t work so I proceed to your next suggestion.

                • Anup Raman Jun 25, 2013, 3:31 pm

                  Please send me the log file to check if the ipaddress is changed.
                  If the issue is not fixed, try to restart computer in safe mode with networking and check if it is working. If yes, there should be an issue with software blocking it.
                  If you have done all the steps mentioned in this article properly, there should not be any reason why you should not get internet connection unless it is an issue with ISP. Contacting them might help.
                  Finally, there is one more thing which I hate to suggest. Try to do a system restore. Restore your computer back to a date when everything was working. System restore had fixed plenty of issues in the past where none of the methods worked. The problem is, you may never know the source of the problem and if it returns in the future. Anyway try it.
                  This time I really hope everything works fine.

                  • kenneth Jun 26, 2013, 2:21 pm

                    There’s an unspecified error occurred during system restore. (0x80070002)
                    There are no problem with my ISP cause my cousin used OTHER laptop and it worked fine

                    I don’t know what is the cause of it, I tried everything. I don’t know why they did not work at all

                      System restore error might be associated with a corrupted security software. Try uninstalling security software and check the result.

    I have tried all the suggestions and am still having problems. I am running windows 8 and have a usb network adapter, but I am getting the notice that “the dns lookup failed” and my connection shows that I have “no internet access.” But my laptop is connected just fine. I have tried all the commands and uninstalling avast. I have tried disbling Ipv6 but it doesn’t help. I am sending this through my S3, please help

    • Anup Raman Jun 19, 2013, 6:33 pm

      which browser have this problem? did you try with a different browser? let me know the results.

      If the error is popping up for only one browser, it might be an issue with the browser. Check for unnecessary add-ons attached to the browser and remove it.

      • Michael Jun 19, 2013, 9:04 pm

        I was mistaken, the laptop was not connected to the internet. All devices are able to connect to the network but with no internet access. It is not the browser as I tried using internet explorer on both instead of chrome and am still unable to connect. So far I have been unable to fix the connection on any of my devices.

        • Anup Raman Jun 20, 2013, 8:00 am

          Hi Michael,

          Clearly this is not an issue with any of the device that you connect. All devices are able to connect to network means router should be working fine.

          You need to check if this is an issue with modem.
          The other possibility is that modem and router connection is not properly configured.

          For modem issue, doing a power cycle is the most you can do.Do the below steps.
          1)Shutdown your system,
          2)Power off any router connected to your modem,
          3)Power off your ISP Modem
          wait at least 30 seconds, and restart in this order
          1)power ON the modem; wait one mintue for it to stablize
          2)power on the router and wait 30 seconds
          3)Start your system

          Check the status. Check if the modem lights are properly turned on.
          Check if all the devices in network is able to get internet. If not,
          Use the network cable to connect modem and laptop.check the internet connection. If the internet is working, modem is fine (If internet is working, the problem is with configuring modem and router.Check the user manual and configure it properly or get help from ISP to help configuring it properly)
          If the issue seems to be with modem itself, contact your ISP.

          ISP technicians have a tendency to pass on the blame in complicated cases.Use this article as a reference and let them know that you tried all that is mentioned here.Once cornered, they should be able to help.

  • Phil Jun 3, 2013, 11:15 pm

    Thank you, thank you, thank you. I have been wrestling with this problem for over a week, I even went out & bought a new wireless dongle and was seriously considering a reformat. None of the other websites I tried suggested booting in safe mode. As soon as I saw the google logo come up in safe mode I took heart. Booted back up, disabled zone alarm firewall and activated windows firewall and all was good in the world.

  • Sammy May 6, 2013, 2:38 pm

    I tried to disable the local area connection and troubleshoot again and I had this message. YOUR COMPUTER APPEARS TO BE CORRECTLY CONFIGURED, BUT THE DEVICE OR RESOURCE (DNS SERVER) ISN’T RESPONDING.

    • Anup Raman May 6, 2013, 5:31 pm

      Only 2 reasons why you have the problem now.

      1) The computer is not able to communicate properly because of the presence of firewall or security software.
      Solution: Restart the computer in Safe Mode with Networking and check if the connection is working fine. At times even Safe Mode with Networking may not help. I highly recommend, remove all security softwares from the computer including firewall and check the status of this issue. Make sure you dont have any outdated security software which is still running without your knowledge. Check Control Panel -> Programs and Features and confirm that. After removing all security software, check the status. You can re-install security software back, once the issue is fixed.

      2)The router is not properly communicating with modem. This is usually an ISP issue or an issue with modem or router.
      Solution:
      a) Powercycle Modem. Turn off the modem and router. Wait for a minute and then turn it on. Maybe you can restart the computer as well and check if it is working now.
      b) Contact your ISP. Inform them what all you did till now and check if they can find any issue with modem or router.

      Good Luck

        Hi, Anup

        I am having the same problem “DNS server not responding” in windows 8. i can connect to the wifi from my school but not the one from my apartment.

        please help,

        Thanks

        • Anup Raman May 28, 2013, 12:57 am

          Since wifi is working fine at school, the problem is not with your computer but problem with modem or router.
          Powercycle the modem.turn off all the devices including modem,router and then turn it back on after a couple of minutes.
          check the led lights are blinking right.

      Exclamation mark seems to me there is some sort of conflict mainly an IP conflict. Assuming that you are using a router and sharing multiple devices,try this.
      Go to ncpa.cpl as mentioned in the article,
      open properties by right clicking on network connection,
      Click Internet protocol version 4,
      click properties,
      select Use the following ipaddress.
      Put the ipaddress 192.168.1.4 subnetmask 255.255.255.0 Default Gateway 192.168.1.2.
      (By assigning a preferred ipaddress we are reducing the possibility of conflict with other devices in the same network)
      Please note: If your computer is already configured to use the following ipaddress, then change it to Obtain ipaddress automatically.

      Check if that fixed the problem. Restart computer and check if the problem comes back.

      Let me know the result.Good Luck 🙂

    • Sammy May 5, 2013, 8:39 pm

      Pls was told dhcp is not enabled for wireless.

      • Anup Raman May 6, 2013, 3:39 am

        Step 1
        Open Run window
        type services.msc
        In the list, check if DHCP client is enabled. (If not enabled, then right click on it, select properties and then click on start. Also make sure the startup type is automatic)

        Step 2
        Open Control Panel
        click Network and Internet
        click Network and Sharing Center
        click Manage wireless networks from left.
        select the wireless network and right-click
        select Properties
        On Security tab disable all options i.e., in Security type select No authentication (Open) and in Encryption type select None.
        Also enable the automatic connectivity and SSID settings
        Go to connection tab
        Select “Connect automatically when this network is in range ” and “Connect even if the network is not broadcasting its name (SSID) check-boxes.

        Step 3
        Open Control Panel
        Open Network and Internet
        Open System and Security
        Open Windows Firewall
        click Restore Defaults

        Hope this helps

        • Sammy May 6, 2013, 7:14 am

          I rely appreciate your help. But I have tried the steps you outlined but there is still an exclamation sign on the network sign which prevents me from accessing the Internet. And wen I troubleshoot it am told WINDOWS CAN’T COMMUNICATE WITH THE DEVICE OR RESOURCE (PRIMARY DNS SERVER). Please am counting on u.

          • Anup Raman May 6, 2013, 9:14 am

            What happens when you change the preferred DNS address to 8.8.8.8 and alternate address to 8.8.4.4. This is explained under the topic How to fix DNS Server Not Responding Error Normally. Please update the result.

            • Sammy May 6, 2013, 2:30 pm

              Still having THE DNS SERVER ISN’T RESPONDING after that option. With the exclamation sign still on the network sign.

  • Sammy May 4, 2013, 12:20 pm

    Am having a similar problem. Am using hp pav dm4. The Internet sometimes work with Skype ba when ever I try to open a browser, an exclamation sign appears on the network symbol. I have tried ur procedure ba it’s still not working out for me. The Internet works alright on the iPad though . Trusting u for help

  • Mrunal May 3, 2013, 2:07 pm

    Hi Anup,

    I was having same exact problem. Came to your site and I did that google DNS and disabled IPv6 as per your advice.
    Now the net is working fine again.

    Thanks for this informative article, keep writing, best wishes.

    Hi Anup,

    This is a great article but I have tried all the possible fixes listed here with no luck. I’m using Samsung N150 Plus netbook, windows 7. Anymore ideas for this issue?

    Thanks in advance.

    Regards,

    MC

    • Anup Raman Apr 12, 2013, 3:13 pm

      Hi MC,

      Please send the details.

      1)are you using any other computer or mobile device to connect internet and do they have the same prob?
      2)which security software do you have on the computer and is it still turned on.did you try safe mode with networking?
      3)start-> cmd -> ipconfig /all.This will show you all the ipaddress details
      Right click on the details->select all-> ctrl+c .Paste it on a notepad. Please send me the log file.

      Regards
      Anup

  • Mike S Mar 17, 2013, 2:13 pm

    Hi Anup, I’ve been having this problem for months and have found a few different places that offered solutions. Yours is by far the most detailed and easiest to follow, so thank you for taking the time to help all of us. I am currently having this issues. I would finda solution that works for a few days or a week or a month, but then it comes back. The only thing i haven’t tried that you suggest is uninstalling McAfee. However, when I tried to run the command prompts that you offer, I get an error that says I don’t have elevation, or enough elevation. I don’t know what this means and I couldn’t get it to go away…. Can you help? I appreciate anything you can tell me….

    • Anup Raman Mar 18, 2013, 4:06 am

      Thanks Mike for the feedback.

      “The requested operation requires elevation” This message is displayed when the command prompt or any tools requires admin rights to perform its function.
      Try this.
      click start -> type cmd in the search window
      cmd will be displayed in the list. right click on cmd. select “run as administrator.
      Now you should be able to run any task in command prompt as it has admin rights.

      Uninstalling McAfee was a solution sometime back when they screwed up their software during an update. But now it is working fine. However considering security software is one of the major cause for most DNS issues, it is worth uninstalling and reinstalling security software once every few months(say 6mths)

      Hope this helps.

      • Mike S Mar 19, 2013, 5:28 am

        Hi Anup, and thank you for getting back to me. I really appreciate you taking the time to help me.

        I figured out what the ‘elevation’ error meant and how to get by it, but I still had the DNS issue after successfully running the commands. I also uninstalled McAfee and closed the firewall on Windows Defender, none of which solved my issue either. The only security software that I didnt touch was Spybot. I even did a system restore to a time when I know the internet connection was working, and even that didnt help. Unless you have any other suggestions, I guess I need to try calling my ISP, which is Cablevision.

        Thank you again….

        (Copied from email)

        • Anup Raman Mar 19, 2013, 5:24 pm

          Hi Mike,

          Thanks for keeping me updated

          Since you are sure that you already tried all the steps mentioned here, please contact your ISP to get it fixed. You can even give this article as a reference and tell the technician that you already followed the steps mentioned here. ISP technicians are well trained to quickly try couple of steps, if it don’t work blame computer or OS problems for fixing the issue.(How I know that? 10+ yrs as a tech support guy taught me lot of things) Dont leave them until they get the issue fixed for you. Kindly update the result.

          Good Luck
          Anup Raman

          • Mike S Mar 21, 2013, 1:50 pm

            Hi Anup… Thank you again for your time and patience. I am not sure what caused it, but when I logged in later Monday night, my internet connection was working. I reinstalled McAfee before I went to bed, then Tuesaday afternoon the internet wasn’t working again. I changed the DNS server settings to the Google universal, to no avail. So I shut down my pc, unplgged my router and modem, waited a few minutes, and turned everything on, and it worked again. I am thinking I have a virus or malware, so I downloaded McAfee Stinger and ran it, but it didnt find anything. Any thoughts?

            • Anup Raman Mar 21, 2013, 1:59 pm

              Hi Michael,

              I dont think this is any issue with any malware. Getting internet connection intermittently itself is a proof that things are working fine at your end. I have gone through similiar situations, but fortunately for sometime just turning off and turn on the modem worked fine for me. Finally I contacted my ISP and they got it fixed impermanently after replacing modem. We just need to make sure that our side is working fine.

  • Colin Burns Feb 22, 2013, 2:35 am

    Anup,
    I am experiencing the same problem as rageofgod and followed all the steps you prpvided and am still not getting the dns to work. Please help!

    • Anup Raman Feb 22, 2013, 2:51 pm

      Could you please check if the internet is working fine in Safe Mode with Networking. Also could you please use the command ipconfig /all and send me the details.

  • Cody Jan 17, 2013, 10:07 pm

    Anup Ramon!!! I am having similar problem as rageofgod…. i followed every step you suggested and thought I fixed it when i restarted the DHCP Client… however it will only open one web page at best before it goes back to ‘No Internet Access’ with DNS error… any ideas? I have about lost all hope.

    • Anup Raman Jan 18, 2013, 3:30 am

      This should be an issue with firewall or a software blocking the connection.Did you try disabling firewall?

  • Roy Jan 4, 2013, 5:42 am

    Fantastic treasure trove of information!
    I stumbled upon you whilst looking for solutions to this frustrating DNS error – its now fixed, hopefully, but the thanks still go to you for providing all this information.
    I don’t use McAfee, I use Avast, but I can’t help wondering if any of the popular, free-to-use AVs have this problem with blocking the internet.

    • Anup Raman Jan 6, 2013, 4:37 am

      McAfee did an update which terribly went wrong and that’s why they had this problem.But they were soon to come with a solution.In their next update, they fixed the issue.
      These issues happen when there is a coding error or when a configuration settings is changed automatically by the security software.
      My point is it can happen to any security software, no matter if it’s paid or the free ones.Issues like this had happened in the past and will definitely happen in the future,We have to live with it.

    I’m having this problem with my laptop in only one place…college. The internet here isn’t the best to begin with, but for the first month and a half I’ve been going here it has connected fine. All of a sudden in the past week or so it will connect to the internet, but it says “no access”. When I go home it works fine, but when I’m here it won’t work and when I troubleshoot the problem it says “windows can’t communicate with the device or resource ( primary dns server). What could be the problem? My ipod touch connects fine by the way.

      Hi Alex,

      Considering internet works fine at home narrows down the issue is only with college connection.

      Try safe mode with networking in college.If it works fine, security software might have accidentally blocked your college connection.
      Creating a new network connection for college is another solution.

      Please update me on the result.Good Luck

    Hi,
    I had a similar problem (DNS server problem and slow Internet connectivity) since McAfee expired after the free period. I uninstalled McAfee, removed all security services and tried everything suggested here.

    Finally I confirmed in safe mode the connection worked fine. My ISP was not the issue since I was able to use my laptop and my iPad on my Cisco router. But my desktop Internet was still very slow.

    I also tried to stopped all the services to simulate the safe mode configuration and I still had the same Internet connectivity problem (slow access to any websites).

    I finally decided to just install another browser (the latest Firefox version) to replace IE 9 and it solves the situation!!

    Internet Explorer 9 seems to be my problem. Maybe you will have another cleared and detailed explanation to describe this issue.

    Thanks for your nice post to help me troubling shooting my issue.

    • Anup Raman Oct 14, 2012, 9:29 pm

      Glad to know that issues are fixed in your computer.I personally prefer firefox or chrome over IE.However if you like to use IE,try doing an IE optimization.There is also a video tutorial explaining the steps.I am sure, it will fix it.

      It’s amazing to know how different issues can be and every details is another learning experience, which in turn I keep adding to my articles.Thanks very much for taking time to give me feedback.

        • Anup Raman Oct 12, 2012, 5:19 am

          Hi,

          Your English is fine. I am only worried about your DNS problem 🙁

          Try this
          Go to control panel -> administrative tools -> computer management -> select “device manager” on the left side. This will list all the devices installed on your computer on the right side. Expand “network adapters” which will show you all the network adapters listed there. Uninstall all the devices listed under network adapters and then restart the computer. Since the OS is Windows 7, all the drivers should get installed automatically after restart. Check if the issue is fixed.

          If not fixed,then this is complicated.I hate to say this, but try doing a system restore to a point when the computer was working fine.Follow the instructions as mentioned in link http://www.sevenforums.com/tutorials/700-system-restore.html.

          Let me know the result.In case, not fixed I will come up with some solution. Please give me at least 12hrs to reply.

          • rageofgod Oct 13, 2012, 5:36 am

            And your. Step to uninstall network adapter. It still dns not responding.
            TThe problem is I don’t have any back up before my pc error.. What must I do??? And how to
            Reinstall pc if that the only way… And thanks for anup raman fast replay..

            • Anup Raman Oct 13, 2012, 6:59 am

              Hi,

              🙁 getting tough. Still not able to understand where it went wrong.I hope you tried all the troubleshooting as mentioned in this article.Please note that I added some additional info after coming across this issue. (I still doubt if any security software is preventing you from getting internet access.remove all if you have any.) Please contact your ISP and check if it is their problem.It’s important, as if this issue is from their end,then there is no point in re-installing everything from start in your computer.You may end up still having the same issue.

              Also please send me the following details
              start-> cmd -> ipconfig /all.This will show you all the ipaddress details
              Right click on the details->select all-> ctrl+c .Paste it on a notepad. Please send me the log file. It might help.

              Hope we can fix this soon.Good Luck

                      Hi,

                      Checking the ipconfig /all, I am more convinced that this is an issue with some software or program blocking internet connection.I know you removed McAffee.Try these steps.

                      1)Open control panel ->windows firewall ->advanced settings on the left side -> Restore default policy on the right side. This should help you to reset the windows firewall to default settings.
                      2)Go to Run -> type appwiz.cpl. Remove if you have any security softwares (even the ones which expired in the past or not being used) and if there is any unwanted software in the list.This can be a clean up as well.
                      3)Go to Run -> services.msc. Right click on service name DNS client and then restart it. If it is already stopped,select start the service. Do the same for DHCP client. These are essential services for your computer.Check if the issue is fixed.
                      If not, go through the entire list of services. Check if you have any other services related to McAfee or any other security software.Right click on the service and select disable.check if the issue is fixed.
                      If not,disable services such as windows firewall and windows defender.check if the issue is fixed.Please make sure you enable the service, if it is not responsible for this issue.

                      If none of this fixed,Please let me know the answers for the following?
                      1)Did you check with your Internet Service Provider? Have they said,it is not their problem?
                      2)Do you have any other computer or mobile in the network using the same internet connection? if those devices are not working, then it should be an issue with ISP.

                      I am really out of ideas here.Almost all forums and website explains the same exact troubleshooting steps that I mentioned here.However there is one different article in this link .Maybe that helps.Keep me updated.

                      Good Luck

    hello there Anup,
    PLEASE HELP!! My sister has come to visit me and her laptop is connecting to our wireless but it says no internet access. then says DNS not responding. we’ve tried typing ncpa.cpl and it only comes up with some bluetooth network in internet connections. what do we do?

    We appreciate your knowledge to help us,

    THaNK you

    • Anup Raman Sep 24, 2012, 3:51 am

      It seems you haven’t established a wireless connection.

      Turn off wireless router for couple of mts and then turn it on.This will help in power cycling.Check if you are able to get internet connection.

      If not, open command prompt with administrator rights. Execute the command in the following order.
      ipconfig /flushdns
      ipconfig /renew
      netsh winsock reset
      The last command will ask you to restart the computer.After restarting, check ncpa.cpl for any new wireless connection.

      If not create a new wireless connection manually by going to control panel->Network and Sharing center->create a new connection.

      Please share the result

      • lacey Sep 24, 2012, 6:15 am

        Hey Anup,
        I tried the command promt thing and that didnt change the no internet access problem. I then tried to manually create a new wireless connection and that didnt seem to help either. in the cmd it came up with media disconnected. does this have anything to do with my internet?
        Thanks,
        Hope something works soon 🙂

        • Anup Raman Sep 24, 2012, 6:56 am

          hmmm…..It seems complicated.I hope you already tried setting the DNS address to 208.67.222.222 and 208.67.220.220.

          There is only solution that I can think about. Why don’t you try to disable the security software and check if that fix the issue.If not, try uninstalling the security software.If the security software is corrupted, disabling won’t help. I beleive the security software settings is blocking the computer from accessing wireless network.

          Lacey, I hate to give this suggestion for 2 reasons
          1)What if this didn’t fix the problem? Then you will end up not having internet as well as system protection.
          2)Do you have a backup plan or have the resources to re-install security software back later.

          Do keep me updated
          Good Luck

        • Anup Raman Sep 25, 2012, 6:52 am

          Just a quick thought on steps before removing security software.This can be done only if have a wired internet connection.

          Connect to internet using a wired connection. Check if there is any connection. If not, restart computer in safe mode with networking and check internet.If there is a connection, then it is surely the security software creating the problem.

          If you are getting internet in normal mode using wired connection, then it might be a problem with the service WLAN autoconfig.Go to Run->services.msc->WLAN autoconfig->open properties. Check if the service is running. If not,start the service.If the service is already running, stop it and restart the service.

          Hope this helps.

  • James Sep 20, 2012, 9:05 pm

    Anup, you are my god damn hero! McAfee problem over here too.

  • Stu Coolidge Sep 13, 2012, 2:22 am

    Still nogo…I don’t have McAffee, and even disabling windows firewall and following all steps didn’t fix the issue…does the fact that I use an HP laptop change anything?

    • Anup Raman Sep 13, 2012, 4:18 am

      Did you try safe mode with Networking? If the internet works fine in safe mode with Networking, then uninstall the security software.I got a feeling that is the case here.

  • LAS Sep 7, 2012, 9:23 pm

    Awesome, helpful information! We were very frustrated and found your troubleshooting….it was McAfee! Thank you so much.

  • Eaters Sep 4, 2012, 9:11 pm

    The DNS problem was driving me crazy. had tried everything – repeatedly! Then found this blog. Not sure if it was mcafee or the dns cahe clearout that solved it but I have done both and now back in business. Have removed mcafee from both my computers and have now just removed mcafee from my wife’s computer ( trying Microsoft Security Essentials) Touch wood our marriage will now stay in place!

  • R Sep 2, 2012, 6:59 pm

    Yup, it was McAfee…. THanks for the tip–you savedus $150 !

    • Anup Raman Sep 3, 2012, 7:06 am

      🙂 Wonder, what $150 is for? Glad this info helped.

  • Noneya Aug 26, 2012, 7:52 pm

    Seems like mcafee needs to be more careful. Uninstall fixed it right away. Literally 1/3 way into uninstall I got my Internet back haha

  • Jon Aug 25, 2012, 7:19 pm

    Same thing! wife was having the DNS Error and I am deployed overseas, I luckily found this blog and comments and as soon as she uninstalled McAfee, bam! internet was back. I like to think I am somewhat knowledgeable about networks and what not but this one was stumping me. We tried everything… thanks sooo much!!

  • John Perks Aug 25, 2012, 2:40 pm

    WOW! That McAfee suggestion was right on the button. As it was removed I got my access back.

  • J,R, Miller Aug 25, 2012, 2:34 am

    Terrific suggestion. I downloaded the McAfee update yesterday and today, no internet. I tried everything including suggestions from all of the other results in a Google search. After an hour of frustration, i ran into this page. Your suggestion worked fantastic. As soon as i removed McAfee, i had internet. I then reloaded it and have no issues.
    THANKS!

  • Ash Aug 25, 2012, 1:36 am

    Uninstalling McAfee worked for me also! Thanks for the tip!

  • Brennan Aug 25, 2012, 12:45 am

    The second the MacAfee uninstall was complete my internet started working again for me.

  • joey Aug 23, 2012, 10:14 pm

    im the third person in a week that uninstalling mcafee alowed me to fix the dns error that makes me think it must of been something with a recent update time for free anti virus anywayy

    • Anup Raman Aug 24, 2012, 5:35 pm

      Strange. I have contacts in McAfee worldwide support team.When I enquired, none mentioned anything like this happening. They will definitely let me know if any major issue is happening. Will update in couple of days.

  • bhavya Aug 22, 2012, 1:49 pm

    uninstalling McAfee worked for me, thanks 🙂

  • luckydip Aug 20, 2012, 3:18 am

    I had the problem for two days. Several systems restores fixed  the issue for a short period of time. Checked for viruses in safe mode with networking. Internet worked just fine in a safe mode with networking… I also tried to tweak Mcafee Internet Security that came with my Dell laptop. Disabling firewall and antivirus did not work. Downloaded a couple other virus malware killers and scanned in safe mode with no luck. They could not find anything. Finally I uninstalled McAfee… And voila! I installed Microsoft Security Essntials: it is free and my Internet works!!! I used to work in a call centre for Dell: problems with McAfee blocking the Internet were a real nightmare. So, if you have this issue with DNS server not responding, look at your antivirus first… Do you really need that one particularly…

    • anupraman Aug 20, 2012, 7:24 am

       @luckydip In this case, you missed the clue in the beginning itself. The internet worked fine in safe mode with networking. It was obvious that the issue is created by some third party software. 90% of all third party issues is created by security software. Not to blame any security software. Even the best security software if not configured correctly create lot of problems. The solution is simple, just uninstall and reinstall.
       
      Good to see the issue is fixed. Cheers….!

  • Mathew Jun 21, 2012, 2:36 am
