I am attempting to connect to an exchange server over the internet through an ISA server.
The client works fine when using the proxy client 2.0 server. However, with the same ports open on the isa server, i have no luck. The hosts file is setup correctly. If i open all IP traffic on the isa server in protocol rules it works correctly.
These are the ports I have open. sounds to me like I need some other port open for this to work?
