Greetings Pat,

The easiest way would just to put a bad entry in the Windows hosts file.

To do so, open up Notepad, click File, then Open, and enter
"%windir%\system32\drivers\etc\hosts" and click OK.

You'll see a 127.0.0.1 localhost entry. Simply make a new line after that, and add:
127.0.0.1 webmessenger.msn.com

Then save the file, and after a reboot, they won't be able to access the Web Messenger
anymore.
