Because it's impossible to confugure ISA behind CISCO, I put a cable to go from the Switch to the HUB, and plugged into hub my ISA and Router. I guess I wanted to go arround our CISCO Firewall. Internet on ISA worked, I got VPN working (Europe-USA). Before I continued my NEW FIREWALL configuration, I started having problems with Microsoft Exchange (New Mailbox cannot be added...or...email not received internally--sent internally). When I shut down ISA and restart my Exchange, I have no more problems with Exchange. As soon as I power on my ISA, weird things start happening with MS Exchange. All our servers an workstations run Win2000. ???Has anyone heard about this problem? ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: steve@xxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
