DNS Server Not responding

Quickly Fix ‘DNS Server Not Responding Errors’ on Windows 10

Understanding the DNS Server Not Responding Errors

DNS or Domain Name System is a server that translates website addresses (language which computers can understand) so that your browser can connect to them. DNS allows you to browse a website online simply by typing the domain name instead of the IP address. Put simply, the DNS server is the phonebook of the Internet.

When you connect a device to your home network or a Wi-Fi hotspot with internet access, the internet connection may fail to work for a lot of several reasons.

In this article we will talk about a particular category of reasons, which is DNS errors. Windows 7, Windows 8.1 and Windows 10 computers may report the following error messages in the Troubleshooting Problems found window:​

 “DNS server not responding”

It may also show up with the websites name along with the message ‘Server DNS Address could not be found.’

The DNS server not responding error on Windows is one of the most common issues. If you get this error on your Windows PC, the device will not be able to reach the internet.

Your PC might appear to be correctly configured, but the device or resource (DNS server) is not responding.

The DNS Server not responding error occurs when one portion of a network is not connecting properly to another portion of the network (your device). DNS errors are one of the most common errors users receive while surfing the Web.

This can occur because of a wide range of issues which we’ll tackle in this article.

One of the most common problems associated with a DNS error is a down network. A single server in the system may not relay the information correctly to the next server. Or a setting may be wrong, or something as simple as a cord connected incorrectly to an added server.

Let’s try narrowing the range of issues:

Connect to a different device

First, try to connect a different device like a tablet or someone else’s laptop, either using Wi-Fi or a wired computer network (Ethernet). If you can connect a phone, tablet, or PC to the network and access the webpage that you’re having trouble with on your primary device, the issue is clearly with the device and not the router.

Not being able to connect with the second device doesn’t necessarily mean that the router is the problem. If you’re having trouble with a specific website, try accessing it using mobile data. But if you still can’t access the site, the issue is on the site’s end.

Disconnect from VPN

If you use a Virtual Private Network (VPN), make sure that it’s disconnected before you try to access the website that gives you the DNS error message. It’s because VPNs added a new layer to networking that might cause issues when misconfigured or when it’s not running correctly. It’s important to disconnect from your VPN before performing any fixes.

Run Windows Network Diagnostics

On Microsoft Windows PCs, Windows Network Diagnostics can be run to help diagnose internet connection problems. If you’re not sure whether or not your computer is reporting DNS Server Not Responding errors, follow these steps:

For Windows 10:

  • Type ‘Control Panel’ from the Search bar
  • Select ‘Network and Internet’

Run Windows Network Diagnostics

  • Select ‘Network and Sharing Center’
  • Click ‘Troubleshoot’

Troubleshoot network connection problems

  • Select ‘Ethernet’ and click Next.
  • Once the troubleshooting test finishes, it will display the error messages on the Problems found section

For Windows 7:

  1. Open the Control Panel.
  2. Go to the Network and Sharing Center.

Wait for the troubleshooting tests to complete and look in the Problems found section of the window for the error message.

Solutions:

1. Use a different browser

One of the quickest steps you can try to fix DNS server not responding issue is by accessing the website using a different browser. If your default web browser is Chrome, you can simply switch to Firefox or Opera to see whether it fixes the issue.

If it does, update your default web browser to the latest version or uninstall and reinstall it. However, if the “DNS server is not responding” message still appears, you can proceed to the next step.

2. Restart your modem and router

Simply shutdown your computer, modem+router, then restart them all and try connecting.

This will clear your router’s cache and thus it may resolve DNS errors.

Unplug your modem’s power cable as well as your router’s power cable. Then, allow both your modem and your router to sit for at least 30 seconds. Next, reconnect your modem and wait for it to come back online. Lastly, reconnect your router to your modem and wait for it to come back online.

3. Change the DNS server addresses

The DNS server address is usually obtained automatically, but you can set it to something more reliable. As the DNS server your PC obtained automatically is not responding, you can change it to one of the most reliable DNS servers out there.

For Windows 10:

Type in ncpa.cpl into the Windows search box and press Enter. Or you can also press on the Windows key from your keyboard and start typing which will take you to the search box.

Access Network Connections from Control Panel

a. Choose the current internet connection you are using, right click on it and select Properties

Do the same for Internet Protocol Version 6(TCP/IPv6).

f. Try to access the website you want to go again and see if it succeeds.

7. Update your network adapter driver

You need to head to the device manager window and scroll down to the section of network adapters. Right-click on the active network adapter and click on “Update Driver“.

Update network adapter

If there’s an update available, you should apply it.

After updating your network adapter driver, please restart your computer. Try to access the website you want to go again and see if it succeeds.

8. Upgrade to the latest firmware on your router

Important note: Upgrade failure might cause permanent damage to the router.

It is always recommended to have the latest firmware or software updates applied. However, if you are not sure that this is the issue, we would not recommend you to proceed.

Instead, reach out to an IT expert to upgrade your router’s firmware without confusion. If it’s an issue with the firmware, you should no longer encounter the error after applying the update.

9. Disable antivirus software and firewall temporarily

Although antivirus programs are designed to keep intruders out, they also have the capability to block internet access if they detect a misbehaving device.

Most antivirus programs work using special database (dat) files that the software vendors automatically update on a regular basis. Unfortunately, sometimes mistakes are made with these dat updates that cause the antivirus program to believe a computer is infected when really it is a false alarm.

These false positives can trigger Windows to suddenly start reporting DNS Server Not Responding errors.

To verify whether this is the cause for your device, temporarily disable the antivirus program. Next, re-run the Windows Network Diagnostics. Consult the antivirus vendor for either a new update or technical support.

Disabling your antivirus does not work as a permanent solution, but it works fine in order to temporarily troubleshoot the problem.

10. Disable secondary network connections

Another step that you can try to solve DNS server not responding error is by disabling the secondary connections in your computer and using only the currently active connection.

Here’s how:

  • Type ‘View network connections’ into the search box and click View network connection option
  • A new Network connections window will appear. This is where you can see all of the network connections you have; the ones that aren’t in use will have red ‘X’ marks on them.
  • Hover on the network connection that you don’t use > right click and click ‘Disable’

  • Repeat the above step for all network connections not in use
  • Restart your browser and revisit the website again

11. Disable Internet Protocol Version 6 (IPv6)

Internet Protocol Version 6 is the latest version of Internet Protocol that routes traffic between networks and the Internet. Sadly, it’s also one of the possible culprits of ‘DNS Server not responding’ error, so you can try to disable it to solve the issue.

Here’s the step by step to do this:

  • Type ‘View network connections’ into the search box and click View network connection option
  • A new Network connections window will appear. Right click on your current active connection and select ‘Properties’
  • A new tab will open. Select ‘Networking’ tab and scroll down until you find ‘Internet Protocol Version 6 (TCP/IPv6)’

Unselect IPv6

  • Untick the box if it has been selected, then click OK
  • Restart your browser and revisit the website again

12. Disable Peer-to-Peer Feature

The Peer-to-Peer (P2P) feature allows you to download Windows update once, then use the device to share the updates across all the PCs in your local network. This feature can only be found on Windows 10.

The P2P feature can sometimes interrupt the DNS processes, and you might want to disable it to see whether this will solve the issue. Follow these steps to disable the P2P feature:

  • Type ‘Settings’ in the search box and select the Settings menu
  • Select ‘Update & Security’

Select Update & Security from the Settings menu

  • A new window will appear. Select ‘Delivery Optimization’ from the left sidebar menu
  • Switch the toggle off under ‘Allow downloads from other PCs’

Switch off Allow downloads from other PCs

  • Restart your computer and revisit the website
