Here's the thing:
I have a Win2003 server with 2 NIC's. the server does an important role on network but only needs one NIC. I want to keep this NIC just for this server. On the server though I need to host a VMWare Win2003 server to do a minor role requiring 2 NICs, can I set the VMWare machine to use ONLY the host machines second NIC for all it's workload?
