You might. You might also bnefit from reviewing your ISA WEBEXT..log for those requests to see if ISA is actually efusing them. It's also possible that fedex is using non-standard SSL ports (banks are the biggest offender here).

The server acts as a web proxy for the workstations and we have Small Business Server 2000 installed on a new Dell PowerEdge 2600 (2.4 Xeon, 1Gb of RAM). The most difficult aspect of this problem is that the users constantly remind us that "this problem with the fedex site never happened when we had the old NT server!" So although we've done a great favor for the company by getting their security up to par (thanks to ISA Server), they seem very bothered by this issue that I am struggling to resolve. At this point, I'm not sure if point to point over ethernet is being used. Might I benefit from trying a lower MTU value on the client machines? Thanks again John for staying in touch.
