Windows Systems Administrators must address DNS resolution issues quickly to maintain network connectivity and the smooth running of the internet. DNS, the global technical system that translates URL to IP Address translations, is essential to internet functionality and connectivity – imagine life without Internet….

Here’s an easy-to-follow guide on repairing DNS:

Check Your Network Connection. Verify That Your Computer Is Connected. Check your cable, WiFi and network adapter settings as necessary.

Verifying DNS Settings. Verify all DNS server configurations on your computer using “ipconfig/all”, displaying DNS server data to make sure everything is correct and configured as intended. Verify whether all addresses for DNS servers have been correctly set up.

Consider Switching Servers. Switch your DNS settings between Google (8.8.8.8, 8.8.4.4), Cloudflare (1.1.11.1 and 1.0.0.1) etc to determine if there is still an issue with your connection.

Ping Test. With Command Prompt you can conduct a “ping” test against specific websites or IP addresses in order to test whether DNS resolution for those domains is functioning.

Review Hosts File. Take a close look at the “hosts” file located at C:WindowsSystem32driversetc and ensure there are no incorrect DNS resolution entries in it.

Turn off IPv6 temporarily. Check if it is indeed IPv6 that’s the source of your problems by temporarily shutting it off through Network Connections.

Remove TCP/IP Layer. Launch Command Prompt as an administrator and type in “netshint ip reset” to reset any TCP/IP layers, thus solving network connectivity issues.

How to Restart DNS Client Services. In order to update DNS settings, restart DNS client services using the Services manager console (services.msc).

Install the most up-to-date network drivers. Be sure to update your network adapter, and download and install the most up-to-date drivers from the manufacturer website.

Verify Firewall Settings. Before configuring a firewall, verify its settings are appropriate and won’t block DNS queries.

Run Network Diagnostics. Using Windows Network Diagnostics, it is easy to automatically diagnose DNS issues.
