ipconfig /flushdns have failed!!! function failed during resolution

Posted in
To flush a computer’s DNS resolver cache, just go to Start > Run and type CMD to launch command prompt. Then type the following command: ipconfig /flushdns However, if you get an error that says Could not flush the DNS Resolved Cache: Function failed during execution”, here is how to fix it. The reason why you’re unable to flush a Windows computer DNS cache is if the DNS Service is not running. Go to Start > Run and type services.msc. Double click the DNS Client to bring up DNS Client properties window. Make sure the startup type is set to Automatic and service status is Started. If not, just select the drop down menu, select Automatic and then click the Start button. Now if you run the ipconfig /flushdns command in command prompt, you should see “Successfully flushed the DNS Resolver Cache”.
