Best Configuration for Servers with Multi-Homed Network Adapters

I am looking for the best configuration practice for a Windows Storage Server 2003 with two network adapters, each with two network connections (4 connections total). Currently one adapter's connections are used for virtual machines and the other for the physical machine's connection to the network. Because the physical server NIC has two physical connections to the same network (same subnet, gateway, etc.. different IPs of course) the Windows System log constantly reports NetBT errors about a duplicate network name. I do see, however, a large amount of traffic on both connections. Should one of the connections be disabled, is there another best configuration, or should I just ignore the NetBT errors?

Team two ports (and make sure their respective ports in the switch are configured), that will get rid of the errors in the event viewer; leave the one unused unplugged...

cavp76, does the teaming performance outweigh the TCP/IP offloading gain on CPU cycles?

Usually two-port NICs have a TCP offloading engine incorporated, as they are targeted for server use; so there's no performance penalty (or minimal in any case), you would gain throughput (as it's a storage server).
