Hello, we just upgraded to a "real" server running Small Business Server 2003 Premium with ISA 2004. I have unblocked the port 14683 to allow the XP Pro client program to connect to your update servers, however the virus definition is being classified as "Unidentified IP Traffic" and being discarded. I have tried adding .vpu, .def, and even .stamp to the Content Types with no avail.
I am 100% sure that the clients are able to connect to the update server as after one fails, it tries another and so on. What am I missing? We aren't using the built in proxy for ISA 2004, only SecureNAT and the Firewall.
Thanks,
Andy
