How to Fix "DNS Server Not Responding" on Windows 10

The Importance of DNS

Before diving into solutions, it's crucial to understand what DNS (Domain Name System) does. Essentially, DNS translates human-friendly domain names (like www.google.com) into IP addresses that computers can understand. If your DNS server isn’t responding, your computer can’t access these translations, leaving you disconnected from the internet.

Initial Checks Before Troubleshooting

• Check Your Connection: Make sure your device is properly connected to the internet, either via Wi-Fi or Ethernet.
• Try Another Device: Use another device on the same network to see if the problem is specific to your Windows 10 machine.
• Restart Your Router: Sometimes, a simple reboot of your router can resolve the issue.
• Switch to Another Browser: Occasionally, the problem might be browser-specific. Try accessing the internet using a different browser.

Solution 1: Flush DNS Cache

Windows 10 stores DNS cache that can become corrupted over time. Flushing it can often resolve the issue.

1. Open Command Prompt: Press Win + X and select "Command Prompt (Admin)."
2. Enter the Command: Type ipconfig /flushdns and press Enter.
3. Restart Your Computer: This will ensure the changes take effect.

Solution 2: Change Your DNS Server

If the default DNS server provided by your ISP is down or slow, switching to a public DNS service like Google DNS or OpenDNS can help.

1. Open Network Settings: Press Win + I to open Settings, then go to "Network & Internet."
2. Change Adapter Options: Under the "Status" section, click on "Change adapter options."
3. Access Properties: Right-click your network connection (Wi-Fi or Ethernet) and select "Properties."
4. Set a New DNS Server:
   • Select "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties."
   • Choose "Use the following DNS server addresses" and enter 8.8.8.8 for Google DNS or 1.1.1.1 for Cloudflare.
   • Click "OK" to save your changes.

Solution 3: Disable Peer-to-Peer Features

Windows 10 includes peer-to-peer features that can sometimes interfere with DNS settings.

1. Access Settings: Press Win + I to open the Settings app.
2. Go to Update & Security: Click "Windows Update," then "Advanced options."
3. Disable Peer-to-Peer Updates: Under "Delivery Optimization," turn off the option "Allow downloads from other PCs."

Solution 4: Temporarily Disable Your Antivirus

Some antivirus programs have built-in firewalls that can block DNS servers. Temporarily disabling your antivirus can help identify if it’s the culprit.

1. Locate Your Antivirus Icon: Usually found in the system tray (bottom-right corner).
2. Disable Temporarily: Right-click and select an option like "Disable protection" or "Turn off for 10 minutes."
3. Test Your Connection: If the DNS issue resolves, consider adjusting the firewall settings or contacting your antivirus provider for help.

Solution 5: Update Network Drivers

Outdated or corrupt network drivers can lead to DNS issues. Ensuring your drivers are up-to-date can resolve the problem.

1. Open Device Manager: Press Win + X and select "Device Manager."
2. Find Network Adapters: Expand the "Network adapters" section.
3. Update Driver: Right-click your network adapter and choose "Update driver."
4. Search Automatically: Select "Search automatically for updated driver software." If Windows finds a newer version, it will install it.

Solution 6: Reset Your Router to Factory Settings

If none of the above solutions work, resetting your router might be necessary.

1. Locate the Reset Button: Usually, this is a small pinhole button on the back of your router.
2. Press and Hold: Use a paperclip to press and hold the button for about 10 seconds.
3. Reconfigure Your Network: After the reset, you'll need to set up your network again, including your Wi-Fi name and password.

Final Thoughts: When All Else Fails

If you've tried all these solutions and the problem persists, it may be time to contact your Internet Service Provider (ISP) or a professional technician. They can check if there's a larger issue with your network that needs to be addressed.

Key Takeaway: The "DNS Server Not Responding" issue on Windows 10 can stem from various sources, but with systematic troubleshooting, you can usually get back online quickly. Whether it's a simple DNS cache flush or a more involved router reset, there's a solution that can work for you.
