I'm not sure about 3coms. Intels function with their own software/drivers
that give 2 cards the same IP address, therefore balancing the load across
both NICS.

We have an NT4.0 sp6a server with 2 3com nic cards with discreet tcp/ip
adressess. I added the second card hoping to distribute the traffic but
monitoring both cards showed that they were recieving the exact same
traffic.
Is load balancing the way to fix this, and if so where do I find out how to
do
it.
Thanks,
Robert T.
