Encountering the “DNS server not responding” error can be frustrating—especially when you’re trying to access your favorite websites. This common issue can stem from various network or configuration problems, but fortunately, it’s usually easy to resolve with the right approach. In this guide, we’ll walk you through DNS troubleshooting steps and explain how to fix DNS server not responding errors on both Windows and Mac.
What Is a DNS Server and Why It Matters
The Domain Name System (DNS) translates domain names like www.google.com into IP addresses that computers understand. If the DNS server isn’t working properly, your device won’t know where to send requests—resulting in the dreaded “DNS server not responding” message.

- Incorrect DNS settings
- Faulty router or modem
- Antivirus or firewall interference
- Outdated network drivers
- ISP issues
