DNS Server Not Responding Error – How to Fix it

fix dns server not responding

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.

 

How to fix DNS Server Not Responding Error Normally

  • Open command prompt window by clicking on Run –> cmd (run with administrator privilege)
  • netsh int ip reset c:\resetlog.txt This will reset the ip
  • type netsh winsock reset. This command will create a prompt to restart the computer, don’t restart now. This will help reset winsock settings. Although resetting winsock is not related to this error, this might be helpful in fixing other issues which can lead to this error.
  • type ipconfig /flushdns This will help in flushing the stored DNS cache.
  • Restart the computer and check if the issue is fixed.

Try this step if you still have the same problem.

  • Do a power cycle of modem and computer. Turn off your computer and then turn off the modem and router (if present). Keep it turned off for 5mts and then restart all the devices.
  • Check if the issue is fixed.

Still if the issue is not fixed, try the steps 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
  • 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)
  • Check if issue is fixed. Changing the Preferred and Alternate error usually fix most of the cases.

How to fix 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) Disable security software especially the firewall settings. Then check if the issue is fixed.

If not follow the next step

2)Check if the internet works fine in safe mode with networking

Safe mode is a troubleshooting mode which allows only the essential operating system files and drivers to load.In safe mode with networking, apart from the basic OS files and drivers, network driver is also loaded which enable internet connection.The logic – If the internet connection works fine in safe mode with networking,then third party services or driver is responsible for the problem by blocking the internet connection. If the issue is still not fixed, then it might be some other problem.

How to start computer in safe mode with networking?

  • Shut down the computer
  • Turn it on. As soon as the screen displays, keep tapping F8 key continuously on the keyboard
  • Select “Safe Mode with Networking” (If you use USB drive for internet connection, it won’t work as USB drivers won’t get loaded in safe mode with networking)

Check the internet connection. If the connection works fine, restart the computer normally.Configure security software properly to allow internet connection.
(Note: In certain cases,if the security software is damaged beyond repair disabling or reconfiguring it won’t work . I highly recommend uninstalling the security software.Make sure to re-install it)

 

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 is to now to remove the global DNS and 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)

    • 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

  • 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 6“.

    Restart and check the status.
    ipv6 DNS Server Not Responding Error   How to Fix it

  •  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.

Note: McAfee users may find internet connectivity issues after a recently released update went wrong. The symptoms include problems with security center and loss of internet connectivity. McAfee has already released an update to fix these issues. But if the problem is with internet connectivity, you will have to uninstall McAfee. Once the issue is fixed, you may re-install McAfee as it will have the fix included inside the package.

    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.

    Also I thought I’d add that my internet is Xfinity Blast , not sure if it helps but yea.

    • 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

      • Anthony Contreras

        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

        • 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

          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

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

            • Anthony Contreras

              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

              • 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.

    PLZ HELP ME TO FIX THIS

    • 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

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

        • 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

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

          • ARU

            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?

            • 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

    Nice tutorial…Well explained.No problem in getting it fixed after changing DNS.Thanks Sir….you are doing a great job

  • dMONK

    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.

    • 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.

    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!

  • David

    Thnks buddy…DNS server is responding now :-)

  • ali

    Hi . thank u so much for your good help . my problem solved .

  • Nick

    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

    • 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

    Amazing! Worked perfectly! Thank you so much!

  • Michael

    Hi Anup, Thank you for all tech help. I can now use Wireless internet on my Laptop again.
    Thank you mike x.

  • Peter

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

  • Alphonse

    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.

    • 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

        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.

        • 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

            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

            • 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.

  • Vaidyanathan

        • 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.

    I don’t have problems connecting to the wireless on my mobile devices[tablet and cell phone] and other users on my PC don’t have constant DNS error problems. Why do I continue to have slow connectivity and/or DNS connection issues on my login?? Since it doesn’t happen to others users I don’t think it’s my USB adapter, but don’t know what else to try besides changing my USB adapter. Your help is greatly appreciated!

    • My apologies Patty for the late reply as I was out on a medical emergency.

      Everything here looks fine. Please uninstall your security software and let me know the result. Also let me know which OS is used on the computer.

    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

    :D I found the main cause of my problem!!! It is just my anti virus!!! everything works fine after I uninstalled it…..
    thanks for everything :) sorry for so much stress for me LOL

  • Lilium

    I just wanted to thank you for this very detailed trouble shooting explanation. It was very well written and easy to follow, and it did eventually *fingers crossed* solve my issue! 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! Thank you so much!

    —I’m a complete noob about computer thing I just follow all of your instruction….
    and I’m so thankful that it helps me, but now ALL of them doesn’t work anymore…

    don’t know what happen now

    please help me I know your the only person that could help me to fix my problem

    • 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

      • Kenneth

        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 :)

      • kenneth

        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.

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

            • 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

                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.

                • 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

                    There’s an unspecified error occurred during system restore. (0×80070002)
                    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

    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

    • 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

        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.

        • 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.

    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

    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.

    • 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

        • 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.
          check the led for internet is blinking right.
          check the wireless signal strength
          check if other devices have the same problem connecting to the wi-fi

          Good Luck

    • 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

      Pls was told dhcp is not enabled for wireless.

      • 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

          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.

          • 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

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

  • Sammy

    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

  • 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

    • 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

    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….

    • 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

        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)

        • 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

          • Mike S

            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?

            • 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.

  • Yuxo

    The first method worked well for me! I rebooted and now its working !
    Thank you! : )

  • Colin Burns

    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!

    • 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

    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.

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

  • 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.

    • 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.

    Hello, I am running on Windows Vista, and I too am suffering the DNS Server Error problem. I have tried ALL of the listed solutions, yet I still have the DNS error issue. Is there any way you could help me?

    • Hi Liewy,

      Please give the details.

      1)are you using any other computer or mobile device to connect internet? are they working?
      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.

    Hello,

    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.

    • 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.

        My bad english ..

        • 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

            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..

            • 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

  • ashh

    Thank you soo much you saved me you really did thank god for you

  • lacey

    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

    • 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

        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 :)

        • 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

        • 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

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

  • Stu Coolidge

    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?

    • 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.

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

  • Eaters

    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

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

  • Tom

    same for me today, uninstalling McAfee instantly brought back the internet. Many thanks!!!!!!!!!!

  • Zack

    YESSSSSSS!!!! THIS WAS THE ANSWER!!!!!!

  • Tom ODonnell

    Thanks, uninstalling mcafee solved the DNS issue (Win7).

  • O

    Thank You for the help, uninstalling McAfee really helped and my internet is working now

  • Noneya

    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

  • Drew

    Exact same thing happened to me. I uninstalled McAfee and reinstalled it and I’m back online. Thanks!

  • Kb

    Spot on,, uninstalling Mcafee solved my problem… :) Thank you..

  • Mark

    Thanks! uninstalling Mcfee solved the problem for me at once.

  • Jon

    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

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

  • J,R, Miller

    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

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

  • Brennan

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

  • joey

    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

    • 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

    uninstalling McAfee worked for me, thanks :)

  • luckydip

    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…

    •  @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….!
