Are you facing DNS server issues on your Windows 10 computer? Don’t worry, we’ve got you covered!

In this tutorial, we will guide you through the steps to fix DNS server problems in Windows 10. Whether you are experiencing slow internet connection or unable to access certain websites, these troubleshooting methods will help you resolve the issue and get back online quickly.

Method 1: Restart Your Router

If you are encountering DNS server problems, the first thing you should try is restarting your router. Sometimes, a simple restart can fix temporary glitches and restore your internet connection. To do this:

  1. Unplug the power cable from your router.
  2. Wait for about 30 seconds.
  3. Plug the power cable back in and turn on your router.

This process will refresh your router’s settings and may resolve any DNS server issues.

Method 2: Flush DNS Cache

If restarting your router didn’t solve the problem, try flushing the DNS cache on your Windows 10 computer. The DNS cache stores information about previously visited websites and can sometimes cause conflicts. Here’s how to flush it:

  1. Open the Command Prompt as an administrator. You can do this by searching for “Command Prompt” in the Start menu, right-clicking on it, and selecting “Run as administrator”.
  2. Type the following command and press Enter: ipconfig /flushdns

This command will clear the DNS cache on your computer, allowing it to fetch fresh information from the DNS server.

Method 3: Change DNS Servers

If flushing the DNS cache didn’t work, you can try changing the DNS servers your computer is using. By default, Windows 10 uses your ISP’s DNS servers, but sometimes they can be slow or unreliable. Here’s how to switch to a different DNS server:

  1. Open the Control Panel by searching for it in the Start menu.
  2. Click on “Network and Internet” and then on “Network and Sharing Center”.
  3. Click on your active network connection (e.g., Ethernet or Wi-Fi).
  4. Click on “Properties”.
  5. Select “Internet Protocol Version 4 (TCP/IPv4)” and click on “Properties”.
  6. Select “Use the following DNS server addresses” and enter the IP addresses of reliable public DNS servers such as Google DNS (8.8.8 and 8.4.4) or Cloudflare DNS (1.1.1 and 1.0.1).
  7. Click on “OK” to save the changes.

This will update your computer’s DNS settings and might help resolve any issues related to your ISP’s DNS servers.

Method 4: Disable IPv6

If none of the above methods worked, you can try disabling IPv6 on your Windows 10 computer as a last resort. Some users have reported that disabling IPv6 resolved their DNS server problems:

  1. Open the Control Panel.
  2. Click on your active network connection.
  3. Deselect “Internet Protocol Version 6 (TCP/IPv6)” and click on “OK”.

This will disable IPv6 on your computer, and it might help resolve any DNS server issues you are facing.

In Conclusion

If you are experiencing DNS server issues in Windows 10, try the methods mentioned above one by one until the problem is resolved. Restarting your router, flushing the DNS cache, changing DNS servers, or disabling IPv6 can often fix these issues. If none of these methods work, you may need to contact your internet service provider for further assistance.

We hope this tutorial helped you troubleshoot and fix DNS server problems in Windows 10. Stay connected!
