Binding One IP address to Exchange 2003 Virtual Server

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.

Check the binding order of the NICs, and the default gateway. Exchange gets upset very easily with multiple NICs.
There should be no default gateway on the second NIC and the NIC serving SMTP traffic needs to be top of the binding order.

Having multiple nics on the exchange server will only confuse the server and will result in all sorts of bad behaviour. I would advise you to use exchange with just one NIC, unless it is an sbs.

Binding order was correct with the primary NIC first. Removing the gateway resolved the issue - good job.
