About this tag
DNS troubleshooting on Windows involves diagnosing and resolving issues where a device is connected to a network but cannot access the internet or specific services. Common causes include corrupted network stacks, incorrect DNS settings, stale DNS caches, or problems with network adapters. Windows users can often fix these issues by resetting Winsock and TCP/IP, flushing the DNS cache, renewing IP and DNS leases, or checking adapter configurations. For enterprise environments, DNS problems may also arise during cloud service outages, as seen in the Microsoft 365 outage of January 2026, where DNS resolution failures contributed to service disruptions. This tag covers step-by-step guides and real-world scenarios for restoring connectivity.
