The “DNS server not responding” error is one of the most common internet issues on Windows computers. When this happens, your browser cannot connect to websites—even if your internet seems to be working.
This issue can be frustrating, especially when you need immediate access to the web. The good news is that the problem is usually easy to fix with a few simple steps.
In this complete guide, you’ll learn what causes the DNS server not responding Windows error and how to fix it quickly.
What Is a DNS Server?
DNS (Domain Name System) acts like a translator between website names and IP addresses.
For example:
- You type a website name
- DNS converts it into an IP address
- Your browser connects to the website
If DNS fails, websites won’t load.
What Does “DNS Server Not Responding” Mean?
This error means your computer cannot communicate with the DNS server, so it cannot resolve website addresses.

3. Outdated Network Drivers
