    Couldn't you just block port 80 traffic to the IP's for microsoft.com for
    everybody in your organization? There might not be any legitimate reason
    for individual hosts on your network to talk to the borg on port 80 - I know
    it's that way for a lot of companies. Better yet, block all ports to the
    borg except for smtp to/from your mailservers...

    As far as messenger goes, that uses port 80 as well, but I don't know if it
    can "peer" with other IP's independently of contacting the borg.

    Other options include an installation of WebSense, or a proxy server, and
    then denying urls at the application level.

    I'm having a bit of a nightmare at the moment trying to block these two
    applications with a pix, does anyone know how I can do it?

    Thanks
