My remote W2k clients can connect through the firwall fine, but i have two nt4 clients that cannot connect, they continually recieve time-outs., Does anyone have any idea as to what would be different in nt 4 as to not allow outlook connectivity through ISA ? ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: jim@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
