Not entirely true. *IF* you have cards, drivers, and switches that support
Cisco's FEC standard (Fast Ether Channel) you can get load balancing both
ways. Compaq branded Intel cards and of course Cisco switches will do this.

The best way to implement LB is using IP Metrics software or their
competitor's (forget their name). They will allow you to load balance both
incoming/outgoing traffic.
The software provided by 3Com & Intel only load balance outgoing.
Make sure you have switch, not hub.

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.
