    Never even heard of vuze but the principle is the same as for anything.
    Install something like wireshark or net monitor 3.4 and watch the traffic - this will allow you to see the type of traffic, the signatures and its makeup. Once you have this you can create a deny rule accordingly.

       1900 UDP: Used for UPnP?
        6880 TCP: Vuze uses this port for internal communication. When you launch Vuze, it always checks that port for an older instance of Vuze being already active. If there is an active Vuze, then the new Vuze instance passes the possible torrent name as parameter to the old instance already running and then dies. (This happens e.g. when you click a "download torrent" link on a web page. A new second Vuze instance gets launched by the browser, but it dies after passing the argument to the old Vuze.) If there was no active old Vuze, then the new Vuze reserves that TCP port and starts "listening" there.
        6969 TCP: If you enable internal HTTP tracker, this is the default port used. You need to port-forward this port in router for full connectivity.
        7000 TCP: Default port for HTTPS tracker. (usually not in use)
        16680 UDP: Used for the 'LAN peer finder' functionality.
        45100 TCP: Used for magnet URI handling.
        49001 UDP: Used for Mainline DHT (if that plugin is installed). You need to port-forward this port in router for full connectivity.

    It is very simple.  They cannot use what they do not have.  Uninstall Vuse from their machines.  Do not allow users to be local Administrators on their machines.  If they are no local Administrators they will not be allowed by Windows to reinstall it.  

    Simple as that.

    Keith, is another of the many Torrent clients.

    As far as the Traffic Profile that Linuxo has listed....which was very interesting in explaining how Vuse behaves, BTW........ISA/TMG does not "Allow everything, then deny what you tell it".  Instead it denies everything until you tell it what to allow (principle of least privilege).  Therefore all of those things would already be denied unless it was specifically told to allow them.  So,...get rid of your "allow everything" Access Rule and that will eliminated that.

    Ah - thanks for the clarification, that is why I will never have heard of it. Never come across a company that allows torrent of any form.
