How Do I Fix Windows DNS Server Might Be Unavailable?

Are you experiencing issues with your Windows DNS server? Don’t worry, we’ve got you covered!

In this tutorial, we will guide you through the steps to fix the “DNS Server Might be Unavailable” error on your Windows computer. Let’s get started!

Check Your Network Connection

If you encounter a DNS server error, the first thing to do is check your network connection. Ensure that your Ethernet or Wi-Fi connection is stable and properly connected. You can try restarting your modem or router as well.

Flush DNS Cache

Your computer stores DNS information in its cache, and sometimes this cache can become corrupted, leading to DNS server issues. To fix this, you can flush the DNS cache by following these steps:

  1. Open Command Prompt: Press Windows Key + R, type “cmd” and press Enter.
  2. Type the Command: In the Command Prompt window, type “ipconfig /flushdns” and press Enter.
  3. Restart Your Computer: After executing the command successfully, restart your computer and check if the DNS server error persists.

Change Your DNS Server Address

If flushing the DNS cache didn’t resolve the issue, you can try changing your DNS server address to a public one like Google’s Public DNS or Cloudflare’s 1.1. Here’s how:

  1. Navigate to Network Settings: Right-click on the network icon in your taskbar and select “Open Network & Internet Settings“.
  2. Open Network Adapter Options: Under the “Change your network settings” section, click on “Change adapter options“.
  3. Access Adapter Properties: Right-click on your active network connection and choose “Properties“.
  4. Select Internet Protocol Version 4 (TCP/IPv4): In the properties window, select “Internet Protocol Version 4 (TCP/IPv4)” and click on “Properties“.
  5. Use Custom DNS Server: Choose the option to “Use the following DNS server addresses” and enter either Google’s Public DNS address (8.8.8 / 8.4.4) or Cloudflare’s address (1.1 / 1.0.1).
  6. Save Changes: Click on “OK” to save your changes.

Contact Your ISP or Network Administrator

If none of the above methods work, it’s possible that there might be an issue with your Internet Service Provider (ISP) or your network administrator’s configuration. Get in touch with them for further assistance and provide them with details about the DNS server error you are facing.

In Conclusion

The “DNS Server Might be Unavailable” error can be frustrating, but by following these steps, you should be able to resolve it and regain normal connectivity on your Windows computer.

We hope this article has been helpful in guiding you through the process of fixing this common Windows DNS server issue. Remember to always check your network connection, flush the DNS cache, and consider changing your DNS server address if necessary. If all else fails, don’t hesitate to contact your ISP or network administrator for assistance.
