If you see the “DNS server not responding” error in Windows 11, your computer is unable to translate domain names (like example.com) into IP addresses. As a result, websites may fail to load even though your internet connection appears to be active.
DNS issues are usually caused by incorrect network configuration, router problems, outdated drivers, firewall interference, or problems with your ISP’s DNS servers. Fortunately, most DNS errors can be resolved by adjusting network settings or refreshing the DNS cache.
If you encounter the DNS server not responding error in Windows 11, follow the troubleshooting steps below.
