Hi I am running Windows 2000 Server and ISA 2000 sp2 at a client We need to add SUS to this machine. SUS does not operate on any port other than 80, which is apparently used by ISA. Any way I can stop ISA from using this port to get SUS to use it? Do I just change Auto Discovery to some other port? Strangely enough this issue does not exist on SBS2003 if it is of any assistance Regards William
