Go to My Computer>Dialup Networking.
Right-click your internet connection and select Properties.
A window will open - click the Server Types tab. Click TCP/IP Settings.

For All Other Users:
Go to Control Panel>Network Connections and select your local network.
Click Properties, then select Internet Protocol (TCP/IP). (For Windows 7 users look for the version 4 TCP/IP name)
Click Properties.

You will see a window like the one below - this is the Internet Protocol window. Select "Use the following DNS server addresses" and enter the desired DNS server(s) in the space(s) provided



Now change the DNS to
