How to Fix DNS Server Not Responding Error on Windows

Encountering the DNS Server Not Responding error in Windows can instantly sever your internet connection, leaving your browser displaying a blank error screen even while other devices on the same Wi-Fi network remain connected. This glitch occurs when Windows cannot establish communication with the Domain Name System servers that translate human-friendly domain names into IP addresses.

Fortunately, this is almost always a software or network configuration issue that can be resolved in a few simple steps. Follow this comprehensive guide to fix it quickly.

💡 Quick Check: Test if your smartphone can access the internet on the same Wi-Fi network. If other devices are also failing to browse, restart your home Wi-Fi router by unplugging it for 30 seconds.

Method 1: Flush DNS Cache and Reset Network Protocols

Windows stores cached DNS records to speed up web browsing. If this cache becomes corrupted, connection timeouts occur. Resetting the network configuration forces a clean DNS handshake:

Press Windows Key + S, type Command Prompt, right-click it, and choose Run as administrator.
Type ipconfig /flushdns and press Enter. You will see a confirmation message stating the DNS resolver cache was successfully flushed.
Type ipconfig /release and press Enter to release your current IP address.
Type ipconfig /renew and press Enter to obtain a fresh IP configuration from your router.
Close the window and restart your computer.

Method 2: Switch to Fast Public DNS (Google or Cloudflare)

By default, your computer uses DNS servers provided by your Internet Service Provider (ISP), which can suffer from intermittent congestion or downtime. Switching to globally optimized public DNS servers solves the issue reliably:

Press Windows Key + R, type ncpa.cpl, and press Enter to view your Network Connections.
Right-click your active connection (Wi-Fi or Ethernet) and select Properties.
Select Internet Protocol Version 4 (TCP/IPv4) and click the Properties button.
Select the option Use the following DNS server addresses.
Enter the reliable Cloudflare DNS or Google Public DNS:
- Cloudflare DNS: Preferred DNS server: 1.1.1.1 | Alternate DNS server: 1.0.0.1
- Google DNS: Preferred DNS server: 8.8.8.8 | Alternate DNS server: 8.8.4.4
Check Validate settings upon exit and click OK.

Method 3: Restart the DNS Client Service

Press Win + R, type services.msc, and hit Enter.
Scroll down to locate the DNS Client service.
Verify that its status is set to Running. If greyed out, Windows manages it automatically.

Method 4: Update Your Wi-Fi or Ethernet Network Driver

Outdated network interface card drivers can drop packets and trigger DNS resolution timeouts.

Right-click the Start button and choose Device Manager.
Expand Network adapters.
Right-click your primary wireless or Ethernet hardware and select Update driver.
Choose Search automatically for drivers.

Frequently Asked Questions

Will changing my DNS affect my internet speed?

In many cases, switching to Cloudflare (1.1.1.1) or Google DNS (8.8.8.8) actually improves browsing responsiveness because their global server networks resolve domain names faster than local ISP servers.

Is this error caused by my router or my PC?

If only your Windows computer displays the error while your phone works fine, the issue is on your PC (corrupt DNS cache or bad adapter settings). If all devices fail to load websites, your router or ISP is experiencing an outage.

Conclusion

By flushing your DNS cache and switching to reliable public DNS servers like Cloudflare or Google, you can resolve the DNS Server Not Responding error in under three minutes.
