    What OS? What web server? What firewall?

    I think MSN access' login server "gateway.messenger.hotmail.com" so if you block access to this server.

    Can someone clarify this icon_confused.gif:

    it changes the port each time and the range for the ports to block is large.

    Does HKLM\SOFTWARE\Policies\Microsoft\Messenger\Client\PreventRun=1 reg entry still work?
    (did for older versions of MSN) icon_confused.gif

    Or setting the IP in the hosts files for the server name to 127.0.0.1 or something? Then it doesnt matter what ports it tries.
