Facing ‘DNS Server Isn’t Responding’ Error? Here’s How You Should Fix It

There are times when you are not able to connect to the internet through your PC or laptop. When you try to access a website, your device displays the following message on the screen: ‘DNS server not responding’ or ‘Your computer appears to be correctly configured, but the device or resource is not responding’. 

DNS Server Not Responding on Windows

This error message can appear for a number of reasons. However, the primary reason is server outage. Under such a situation, the server remains temporarily unavailable and thus this error gets displayed on the screen.

What is a DNS Server?

A DNS(Domain Name System) server is a technology that allows the users to get access to various websites easily and conveniently.

Each and every website has an IP address of its own. These IP addresses are a series of randomly placed numbers separated either by dots or by colons. It is not at all possible for human beings to remember such a long series of numbers. Hence comes DNS as the savior.

DNS translates the numeric IP address into alphanumeric domain names. It allows the users to type in the alphanumeric domain name that ultimately makes the website appear on the screen.

What to do when DNS Server Stops Responding?

DNS server error can stop you from accessing the internet at all. It becomes pretty frustrating when you want to reach a particular website but instead, you are constantly restricted to do so. Meanwhile, you get an error message that your DNS server isn’t responding. 

Thankfully, this is not a serious issue. It does not need the intervention or help from a professional technician. You can solve this all by yourself. Here we will provide you with certain technical solutions and fixes that would help you to deal with this problem.

In order to resolve the DNS server error, you can try out these solutions:

1. Deactivate the Firewall of your System

One of the major factors that can cause this error with the DNS server can be the Windows firewall. In that case, you need to disable and pull down the firewall. To do this, at first, you need to go to Control panel. Now, you can deactivate the firewall.

After you have disabled the firewall, check if you can access the website that you have been trying to access previously. If you are able to access, then you can be certain that your firewall is the main culprit that was causing the DNS server error.

If the problem still persists, try out other solutions described below.

2. Restart the Router

Connection problems can be a root cause for the DNS server to not respond timely. You can try restarting your router to check if the problem still exists. 

In case you fail, then you might need the router to give a hard reboot. To reboot the router, pull out the power cord of your router. Now, wait for at least 30 seconds before you power it on again. Check whether you still the same error message.

3. Choosing an Alternate DNS

If restarting the router doesn’t yield the desired result, then you can opt for selecting a different DNS server. Usually, the internet service provider’s DNS server is used for day-to-day operation. However, this can be changed as and when needed. 

Here we will provide you with the steps that you need to follow for changing the DNS server:

  • First, check the Network Connection Settings. Click on the Windows icon situated on the Taskbar and then go to Network Settings.
  • Now, select View Network Connections.
  • You can also enter the command ncpa.cpl.
  • After checking the Network Connection Setting, you need to select the Network Adapter. If you are using a wireless network, then choose WLAN. Whereas, if you are using internet through cable, then choose LAN. Now, right-click on the option and select Properties.
  • Now it’s time to choose the Internet Protocol. Usually, two versions are given: 4 and 6. Choose the one you need and then select Properties.
  • The final step is changing the DNS server address. To assign a DNS server address manually, you need to click on ‘Use the following DNS server address’ and then enter the addresses of other alternative servers.
  • Click on OK after you have manually entered the alternative DNS server address.

4. Flush the DNS Cache and Reset the IP 

Sometimes, clearing out the DNS cache and then resetting the IP can serve as an effective solution for DNS server error. Follow these steps to do so:

  • From Command Prompt, select Run as Administrator.
  • In the black window that appears, type the following commands-

ipconfig /flushdns

ipconfig /registerdns

ipconfig /release

ipconfig /renew

  • Click on Enter.
  • Now, check if you can access the website that you previously wanted to access.

5. Solving TCP/IP or DHCP Issues

TCP/IP utility programs are used to renew and release Windows IP address settings. These TCP/IP networks use Dynamic Host Configuration Protocol services to provide IP addresses to various clients. DHCP provides the device’s primary as well as secondary IP addresses.

You should make sure that both your PC and your router has DHCP enabled in them. If it is disabled in any one of them, then you might possibly face issues with the DNS server.

In conclusion, DNS server error isn’t that serious an issue. Many users face this problem from time to time. So before getting worried and calling a professional to help you out, you can try out these simple solutions to get rid of this issue. We hope the above solutions will prove useful.
