Do yourself a favor; don't ask Mach5 about ISA; they obviously don't have a clue how it (or any proxy, for that matter)works. As far as the IIS log files, that's a by-product of web publishing. Since the Web proxy is involved, your web server sees the request as coming from the ISA, not the external client. Use the data from the WEB..log to compare to the IIS logs.

Unfortunately this answer does me no good since I do not know what to modify/change/alter. ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
