A DNS server is one of the most integral parts of the entire system that allows anyone connected to the internet to access websites and connect to servers. A DNS server is responsible for translating the web address that a person enters into their internet browser’s URL box into an IP address that their computer can easily connect to, allowing them to view and surf the website. In some cases, the DNS server a user is connected to may stop responding to their computer’s requests, resulting in them completely losing any and all access to the internet.
If the DNS server that your computer uses stops responding, you will be completely cut off from the internet, and if you haven’t been living under a rock for the past two decades, you know just how big of a problem that can be. Your DNS server may stop responding either because of an issue on your side (an issue with your computer or router) or a problem with the DNS server your internet connection uses. Fortunately, there are quite a few different methods that you can use on your own to try and fix this problem. The following are some of the most effective solutions that can be used to fix the DNS server not responding problem:
Solution 1: Disable any extra network connections on your computer
Open the Control Panel. Click on View network status and tasks under Network and Internet to open the Network and Sharing Center. In the Network and Sharing Center, click on Change adapter settings in the left pane.
Locate any extra connections that are listed – connections other than the one that is used by your computer to connect to the internet. If any such connections exist, right-click on each of them one by one and click on disable. If you are prompted for administrator confirmation or a password, confirm the action by doing what is required of you.
Solution 2: Power cycle both your router and your computer
Power cycling both your computer and your router can reset their static memories and potentially fix the DNS server not responding issue. To power cycle your router and your computer, unplug each of the two devices from their power sources and then leave them in an unplugged state for anywhere between 60 – 90 seconds. Once the time is up, plug them back into their power sources, boot them up, wait for them to start up completely and then try opening a website in order to determine whether or not the DNS server not responding issue still persists.
Solution 3: Flush your DNS and reset your DNS settings
Click Start -> Type cmd -> Right Click cmd and choose “Run As Administrator”
Type ipconfig /flushdns into the Command Prompt and press Enter.
Type ipconfig /registerdns into the Command Prompt and press Enter.
Type ipconfig /release into the Command Prompt and press Enter.
Type ipconfig /renew into the Command Prompt and press Enter.
Type netsh winsock reset into the Command Prompt and press Enter.
After this restart the system. Close the Command Prompt.
Try connecting to the internet and opening a website. Flushing their DNS and resetting their DNS settings has solved the DNS server not responding issue for many people who have been affected by it.
Solution 4: Change your DNS server addresses
If you have not succeeded with fixing this problem using the solutions mentioned above, there is a good chance that using a different DNS server than the one that is not responding to your computer’s requests will get the job done. To change the DNS server that your computer uses, you need to change the DNS server addresses that have been configured into your network connection’s internet settings. To do so, you need to:
Right-click on the Network icon in your computer’s notification area and click on Open network and sharing center.
Click on Local Area Connection.
Click on Properties.
Click on Internet Protocol Version 4 (TCP/IPv4) to highlight it.
Click on Properties.
Enable the Use the following DNS server addresses option by clicking on the checkbox beside it.
If you want to use Google’s DNS servers as your new DNS servers, set 8.8.8 as your Preferred DNS server and 220.127.116.11 as your Alternate DNS server. If you want to use the DNS servers of OpenDNS – an open-source DNS service, on the other hand, set 18.104.22.168 as your Preferred DNS server and 22.214.171.124 as your Alternate DNS server. Any of these two selections are guaranteed to work. Once you are done changing your network connection’s DNS server preferences, make sure that you check the Validate settings upon exit option on your way out.
Click on OK. Also click on OK in the Local Area Connection Properties
Try to connect to the internet and open a website. Your internet connection should have been restored.

Solution 5: Reset your router
If all else fails, the last of the most effective solutions that you can use to try and fix the DNS server not responding problem is to reset your router. Resetting your router, as simple as it may be, will lead to all of your router’s preferences and settings being reset, which means that when you boot it up after the reset, it will be as though you were booting it up for the very first time. After the reset, you will have to reconfigure all of your router’s settings to your preferences, including your WiFi network’s name and password. To reset your router, you need to:
Get your hands on a paperclip or a pin or any other pointy object.
Locate the recessed Reset button on your router. This button is basically a tiny hole normally located at the back of a router with the term Reset written above or below it.
Put the pointy end of the pointy object you acquired into the Reset button and push it all the way in. Press and hold the button for a good few seconds. This will successfully reset your router.
Once the router has been reset, restart it and then start reconfiguring it.
