How to Fix DNS Server Not Responding Error (Complete Working Guide)

Few things are as frustrating as trying to open a website only to be greeted with the dreaded message: “DNS Server Not Responding.” Whether you’re in the middle of work, streaming, or making an online transaction, this error can stop everything. The good news? You can fix it, and most solutions are easier than you think.

Before diving into the fixes, let’s understand the problem. A DNS (Domain Name System) acts like the internet’s phonebook, translating website names (like google.com) into IP addresses. When DNS fails, your browser has nowhere to go — resulting in the “DNS Server Not Responding” error.

This guide walks you through proven, step-by-step solutions that actually work. Follow these methods in order, and you’ll likely resolve the issue within minutes.

How to Fix DNS Server Not Responding Error

1. Restart Your Network Devices (Simple But Powerful)

Believe it or not, rebooting your router or modem is one of the most effective solutions. Over time, routers accumulate temporary glitches that can interrupt DNS communication.

How to do it:

1. Turn off your router and modem.
2. Wait for 30 seconds.
3. Turn them on again.
4. Reconnect to your network.

This alone fixes the error for more than 50% of users.

2. Switch to a Reliable Public DNS

Sometimes, your ISP’s DNS is slow or temporarily unavailable. Switching to a trusted public DNS like Google or Cloudflare can instantly solve the issue.

Recommended DNS Servers

• Google DNS:
  • 8.8.8.8
  • 8.8.4.4
• Cloudflare DNS:
  • 1.1.1.1
  • 1.0.0.1
• OpenDNS:
  • 208.67.222.222
  • 208.67.220.220

How to change DNS on Windows

1. Control Panel >> Network and Sharing Center
2. Click your network >> Properties
3. Select Internet Protocol Version 4 (TCP/IPv4)
4. Click Properties
5. Choose “Use the following DNS server addresses.”
6. Enter the DNS numbers
7. Save

This single change often makes your browsing faster and more secure.

3. Clear DNS Cache (Fix Hidden Conflicts)

Your computer stores DNS entries to speed up browsing, but sometimes these cached records become outdated or corrupted.

To clear DNS cache on Windows:

1. Open Command Prompt as administrator
2. Type: ipconfig /flushdns
3. Press Enter

You’ll get the message: “Successfully flushed the DNS Resolver Cache.”

Try loading the website again; it may work instantly.

4. Disable and Re-enable Network Adapter

Network adapters can malfunction due to driver issues or temporary bugs.

Steps:

1. Press Windows + R, type ncpa.cpl, and press Enter
2. Right-click your active network
3. Click Disable
4. Wait a few seconds and Enable it again

This refreshes your connection and solves DNS interruptions.

5. Update or Reset Network Drivers

Outdated or corrupted drivers can break DNS communication.

To update drivers:

1. Open Device Manager
2. Expand Network adapters
3. Right-click your adapter >> Update driver

If the issue persists, choose Uninstall device and restart your PC; drivers will reinstall automatically.

6. Disable Firewall or Antivirus Temporarily

Security programs sometimes block DNS traffic by mistake. This is especially common with strict antivirus software.

Try the following:

• Turn off your antivirus for 2–3 minutes
• Disable Windows Firewall temporarily

If DNS starts working, your antivirus configuration is the culprit. Adjust the settings or switch to a more reliable security program.

7. Reset TCP/IP Settings (Deep Fix)

This solution resets your entire network configuration.

Steps:

1. Open Command Prompt (Admin)
2. Run these commands one by one: netsh int ip reset, netsh winsock reset
3. Restart your computer

This thoroughly refreshes all network settings.

8. Try Another Device or Browser

To identify if the issue is device-specific, test the same website on:

• Your smartphone (connected to Wi-Fi)
• Another PC
• Another browser

If the website loads there, your device needs troubleshooting, not your network.

9. Contact Your Internet Service Provider

If none of the above fixes work, your ISP may be experiencing regional DNS issues. They can:

• Restart your connection from their end
• Provide an alternate DNS
• Identify outages or server maintenance

Many users find this to be the final solution.

Conclusion

The “DNS Server Not Responding” error may feel intimidating, but now you know the truth: it’s fixable. Whether it’s your router, DNS settings, cache, or antivirus, one of these solutions will almost always solve the problem.

By following the steps in this guide, you’re not just fixing an error; you’re taking control of your internet connection and ensuring smoother, faster browsing.
