I have an exchange 2003 server with dual NICS. I would like to dedicate the primary NIC to the Exchange Virtual Server and the 2nd to an iscsi NAS device. When I enable the 2nd NIC w/o File and Print (NAS recommendation) and change the virtual server from "all unassigned" to the primary NIC IP address, outbound mail hangs. When the VS is set to 'all unassigned', mail also hangs, I assume attempting the route mail on the 2nd NIC. How do I configure the virtual server to send and receive mail only on the primary NIC. Currently the NICs are on the same subnet.
