DNS Server is Not Responding Error: Solved

DNS Server Not Responding - What will happen when you encounter this error?

Basically, it will interrupt your internet connection. What if you are in the middle of something, when your DNS server stops to respond? You will lose all your online connections, but I suggest you to stay calm as possible as we try to configure it out.

DNS Server Not Responding

DNS Server not Responding Error possible causes

    • It could be that one of your third party software is having a conflict or unintentionally prevent your computer from connecting to the internet, such as antivirus, firewall and network bandwidth controller.

    • It is also possible that your DNS service stops responding or became corrupted due to various reasons, but the most common culprits are virus and computer hardware issue.

    • The other reason might be no reason at all, just kidding. Sometimes DNS Server Not Responding error is caused by the website server that you  are visiting, meaning the fault isn't you or your computer, it's the website server itself.

    Things to be done to help you detect or pinpoint the REAL REASON of DNS Server Not Responding Error

    • Browse the internet using at least three (3) different browsers. If one of your browser can't display web pages then that certain browser is the problem, reinstall it with the latest version. 
    • Visit multiple websites. What if only one of the websites displays the DNS error? Well, be glad because the problem is on that certain website's server not your PC. 
    • If you tried using many browsers and browsing more than three sites, but you still receive a DNS Server not responding, it is safe to say that the issue is in your computer.

    Now that we concluded that there is something wrong in your computer that  cause the DNS Server not Responding error, it's time to troubleshoot it.

    How to solve DNS Server not Responding Error?

    • First, restart your PC, press "F8" to proceed in "Advance Boot Options" select "Safe Mode with Networking" then click "Yes" to enter in safe mode. When you are there, try to connect to the internet, if you can connect, a security software may be blocking your computer to get connected. What if you still receive a DNS Server not Responding Error? A software conflict and corrupted DNS services may be the issue. What to do?
    •  Disable your antivirus and other security software as well as network bandwidth controller, now check if you can connect to the internet. Still, you can't? Uninstall each one by one or all of them. In my experience the "network bandwidth controller" is preventing my PC's TCP/IP to acquire its Default Gateway, thus cause the DNS Server not Responding Error. Although, in most cases removing your security software will solve the error.

    If removing your security software and the network bandwidth controller did not solve the error try this one:

    • Click start, accessories, right click "command prompt" and run it as administrator then, type netsh int ip reset c:\resetlog.txt then input netsh winsock reset (don't restart yet), lastly encode ipconfig /flushdns, now your IP and Winsock are reset while your DNS cache is flushed. Restart your computer and check if it solved the DNS Server not Responding Error. The problem persists?
    •  In your TCP/IPv4 properties try to change it to "obtain an IP Address automatically" if you manually set it to static, if it's already "obtained automatically" switch it into static by filling it with static IP, Default gateway, subnet (if you are in doubt, check this Computer Networks Beginners Guide) and in your DNS section use the following DNS and or the and Not working?

    Fix DNS Server not Responding

    • It's about time to use the system restore, go to "start", "all programs", "accessories", "system tools" then select "system restore" choose the date before the DNS Server not Responding Error occurs. Just follow the wizard's instruction. For more detailed system restore guide, click this How to restore Windows 7. Still having error?

    • Check your router, have it reset as well as  your modem, if possible replace it with your sphere router or borrow from a friend. By the way, before doing that, if you are having a network of computers, remove it first, isolate one unit by plugging your network cable directly to your ISP, observe if it fixes the error. Didn't solve the DNS Server error?

    • Try to reinstall your Operating System, if it does not solve the error, most probably it's a hardware issue. Check if both the green and orange light of your LAN card is blinking. Normally, both lights should be blinking though it's not conclusive, better check your cable with your LAN tester (here's the LAN testing guide). If it's good, time to replace your LAN card.
