- In the run dialog, type cmd and click OK
- When the Command Prompt window opens, type the following in it and Hit Enter.
The ipconfig /flushdns command flushes the DNS cache. A flushed cache erases any modifications int he DNS settings and the system. For a more in-depth, full proof method, use the information below to reset your IP and DNS settings.
