How to Fix the “DNS Server Not Responding” Error: Step-by-Step Guide

Encountering the “DNS Server Not Responding” error can be frustrating—especially when you’re trying to access the internet for work, study, or leisure. This error indicates that your system is unable to contact the Domain Name System (DNS), which is responsible for translating domain names like www.google.com into IP addresses that computers understand. Fortunately, the issue is often resolvable with a few systematic steps. In this guide, we’ll walk you through trusted and effective ways to fix this common internet connectivity problem.

1. Restart Your Computer and Router

Before delving into more complex troubleshooting, try restarting both your computer and your router. This can resolve temporary glitches in network connectivity or DNS resolution.

• Shut down your computer completely.
• Unplug your router and modem from the power outlet.
• Wait for about 30 seconds, then plug them back in.
• Once all the indicator lights are stable, restart your computer.

This simple step often refreshes network settings and can restore DNS functionality.

2. Switch to a Different Web Browser

Sometimes, the problem may lie with the web browser you’re using rather than your network settings. Test the internet connection on another browser to rule out browser-based issues.

• If you’re using Chrome, try accessing the internet via Firefox or Edge.
• Clear your browser cache and cookies if the issue persists.

3. Temporarily Disable Firewall and Antivirus Software

Your firewall or antivirus software might be blocking the DNS service. To determine if this is the cause, temporarily disable both and then check your internet connection.

• Open your firewall or antivirus control panel.
• Disable all protection temporarily.
• Attempt to access a website again.

Note: If your connection works, consider adding a DNS exception or updating your software settings for safe continued use. Don’t forget to re-enable your protection immediately afterward.

4. Manually Change Your DNS Server Address

If your ISP’s DNS server is temporarily down or misconfigured, changing your DNS to a public server like Google’s or Cloudflare’s can resolve the issue:

• Google DNS: 8.8.8.8 and 8.8.4.4
• Cloudflare DNS: 1.1.1.1 and 1.0.0.1

To change your DNS on Windows:

1. Go to Control Panel > Network and Sharing Center.
2. Click Change adapter settings.
3. Right-click on your active network and choose Properties.
4. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
5. Choose Use the following DNS server addresses and input the chosen ones.

After applying, restart your connection and test the internet to see if the issue is resolved.

5. Flush DNS Cache and Renew IP Address

Over time, system DNS caches and IP assignments can become outdated or corrupted. Flushing the DNS cache clears these errors.

Open Command Prompt with administrative privileges and type the following commands one by one:

ipconfig /flushdns
ipconfig /release
ipconfig /renew

These commands will clear the cache, release your current IP address, and request a new one from your network.

6. Boot in Safe Mode with Networking

If the error persists, boot your computer in Safe Mode with Networking. This will run only essential software and drivers, helping identify if third-party programs are causing conflicts.

• On Windows, access System Configuration by typing msconfig in the search bar.
• Go to the Boot tab and check Safe boot with Network selected.

If DNS works in Safe Mode, a background program or driver may be interfering. Consider disabling startups and services to isolate the culprit.

7. Update Your Network Adapter Driver

Outdated or faulty network drivers can sometimes prevent proper DNS functionality. To update your driver:

• Right-click This PC or My Computer and choose Manage.
• Go to Device Manager > Network adapters.
• Right-click your adapter and select Update driver.

You can also download the latest driver directly from the manufacturer’s website.

Conclusion

The “DNS Server Not Responding” error, while annoying, is usually fixable with some targeted troubleshooting. By following the steps above—from simple reboots to adjusting DNS settings—you can methodically identify and resolve the root cause. If none of these solutions work, contact your Internet Service Provider as there may be a larger issue with your DNS routing.
