In Microsoft Windows, you can use the command ipconfig /flushdns to flush the DNS resolver cache. Open the command prompt and type the following:
C:\>ipconfig /flushdns
You should see output like the lines below:
Windows IP Configuration
Successfully flushed the DNS Resolver Cache.
The above command will completely flush the DNS, deleting any incorrect entries too. You can also use the command ipconfig /displaydns to view the DNS resolver cache.
