    I'm trying to get desktop sharing to work using the fat client from an internal client (behind ISA 2006) to an external client. I've got IM working but when I try to do desktop sharing it doesn't connect. I know that desktop sharing is a peer to peer feature and with two external clients, it connects however the client behind the ISA server is not connecting. What rules do i need open on ISA if it is possible? Is it because ISA doesn't do SNAT? i can see the firewall logs showing that it's trying to connect to the internal ip address of the external client. thanks.

    Are you trying to do Desktop sharing from Communicator Client?
    Then this does not work over ISA Server, you need to setup an OCS EDGE Server with A/V EDGE role

    Are you trying to do Desktop sharing from Communicator Web Access?
    Then you must sure that it works internally

    I am kind of lost on this thread, but make sure you have installed ISA 2006 SP1.
