How to Fix DNS Errors on Windows 11

Resolve DNS server not responding and website-not-loading errors.

Last verified: February 21, 2026

DNS errors on Windows manifest most visibly as specific sites failing to load while others work fine, or as the "DNS_PROBE_FINISHED_NO_INTERNET" error in Chrome, both of which indicate the device can't resolve hostnames to IP addresses correctly. The Windows DNS cache retains mappings for visited sites and can preserve stale records after a router's DNS settings change — flushing it with ipconfig /flushdns in Command Prompt forces fresh lookups on every next request. Overriding the router's DNS with a reliable public resolver (Google's 8.8.8.8/8.8.4.4 or Cloudflare's 1.1.1.1) in the network adapter settings is a permanent fix if the router itself is providing unreliable name resolution.

Quick Steps

Follow in order for the fastest result.

  1. 1Open Command Prompt as administrator and run: ipconfig /flushdns. Then close and reopen your browser.
  2. 2Set a reliable public DNS manually: Primary 8.8.8.8, Secondary 8.8.4.4, found in your network adapter or Wi-Fi settings.
  3. 3Restart the browser and test loading sites that previously failed.
