DNS is an acronym for Domain Name System, a decentralized naming system used by all computers, servers, and more devices trying to connect to the Internet.
DNS helps identify your PC and the traffic sent to it, and the system automatically deciphers and displays the necessary information.
This problem may have many causes. Sometimes Windows can mistake a network problem for a DNS problem, while other times it's more likely a third-party application interfering with your network.
A recent update to AVG antivirus appears to be the main cause of this issue, and disabling the update appears to resolve this issue for most users. Use the following tutorial to fix this issue on your PC.
We recommend you start with the first fix, especially if you have third-party antivirus software on your system.
The latest updates to these third-party AVs appear to have created a bug in Windows 11 that causes issues with DNS. However, if the first fix does not work for you, then you can move to other fixes mentioned in the list below. let's start.
If you are using AVG, Avast, McAfee or any third-party antivirus software on your system, then this fix is recommended. The latest updates to these antivirus software and their firewall features appear to break DNS functionality on Windows 11.
The only way to resolve this issue is to completely disable your antivirus firewall, network monitor, and other tools. Once Microsoft or your publisher releases a fix, you can continue to use your antivirus software as expected.
If you subscribe to a third-party DNS service for better connectivity, then we recommend that you re-verify your settings. Updating Windows, your router firmware, or even a third-party network monitor can eventually cause problems with your custom DNS settings.
We recommend that you re-verify your DNS and enter it again to provide new instructions for your network adapter. Once done, just reboot your system and you will no longer have DNS issues with your system.
This is a known method to fix most DNS errors in case they occur due to misconfiguration on your system. Follow the tutorial below to refresh and update your DNS on Windows 11.

If you are unable to resolve the DNS issue, we recommend that you run the Windows Networking Troubleshooter at this time.

Once completed, if you are still having issues, you can continue Fixes mentioned below. However, if you manage to resolve the issue, we recommend you to restart your PC and ensure that you no longer face DNS issues.
Network Monitor and third-party AV Traffic Manager are known to cause a large number of DNS errors.
This usually happens when you get a Windows or network-provided update that attempts to add or remove native firewall rules, which can end up messing with third-party applications. In this case, you can try disabling these applications.
If you finally fix the DNS error, you can disable third-party monitors and managers or try reinstalling them to start over and configure with new rules.
If you are still facing DNS errors, then it is time to pay attention to your router. Power off the router, wait a minute, and then power it back on.
This should help restart your device, which should help re-establish the connection to your network provider. This in turn will also refresh your DNS, which should automatically fix DNS errors for you.
Now it’s time for us to opt for some drastic measures. We recommend you to restart your system in safe mode and see if you are still facing DNS errors. If you do this, you can use one of the other fixes mentioned below.
However, if you are not experiencing DNS errors, it is possible that a third-party application or service is causing problems on your system. In this case, you can try disabling each application to find the culprit. Follow the tutorial below to get started.
Launch the Start menu and click the power icon.
Now hold down Shift on your keyboard and click Restart.
After entering the recovery options, click "Troubleshoot".
Click "Advanced Options".
Now click on "Launch Settings".
Click "Restart".
Select "5" to restart your PC in Safe Mode over the network. This option will allow you to access your internet in safe mode.
Your computer will now restart in safe mode. You can now test your network connection and proceed with the results discussed above.
If you are still facing DNS errors at this point, then we recommend that you run a malware scan to look for any suspicious activity on your system.
We also recommend that you install a Network Monitor to look for any suspicious network activity from your system when it comes to inbound and outbound connections. If you notice any misbehaving apps or programs, let your antivirus software take care of them.
However, if you still end up having problems, you may need to completely reset your PC, including the boot drive, to remove any traces of remaining malware on your system.
If you are using a third-party network adapter or laptop, then we recommend that you look for network card or adapter updates from the manufacturer. A recent hardware update may be required to resolve the issue you are facing.
Most hardware updates these days are delivered directly through Windows Update, so we first recommend that you go to your settings and check for any pending optional driver updates related to your network adapter.
You can use the following tutorial to check for necessary updates.
Press Windows i and click "Windows Update" on the left.
#Click "Check for Updates" and install any network adapter-related updates for your system.
Now click on “Advanced Options”.
Select Optional Updates
Install any optional driver updates available for your PC.
Restart your PC and try to access the network. If you need updated drivers, you shouldn't encounter any DNS errors.
If you are still facing DNS errors at this point, then it is time to restore your system to a location where it was not known to encounter any DNS errors before Recovery point. This will help revert any changes that may have caused this issue, including deleting any third-party applications.
Finally, you can contact your network provider as this may be an issue specific to your connection. The service's support assistant will be able to access your location and evaluate your connection.
Any hardware or software issues with your router or connection can then be identified and resolved. Depending on your network provider, you may need to pay for the services you use.
Resetting is a tedious solution to DNS server problems, but if there are many solutions and the problem persists , you may consider doing this. If you're experiencing any other issues with your PC, a reset isn't a bad idea, all things considered.
