Most of the Intel server NICs can be "teamed" to provide outbound
load balancing, and they are not expensive. It (obviously) requires a
co-operating switch to balance theincoming load. I don't think
they care whether you are running a server o/s or a workstation.
Or you can try to subnet two or more segments to isolate traffic
statically, and then use a router or layer3 switch support to route
between the segments as needed. You can enable IP forwarding
on the workstation using the registry hack, but I don't know that
this would be a good idea performance-wise.
There is also a package out there that spoof arps to pseudo-dynamically
load balance traffic. I can't remember the name, but a search should turn
it up.
My own experience is that all of this is largely a waste of effort --
unless you are just completely maxed out on network bandwidth
and are getting constant jams and collisions.
(With Win2K Pro, I can't imagine what scenario would get to this point,
but people do unusual things.)
You can get gigabit backbone switches and a gigabit server NIC
for a few hundred dollars, and this usually is the way to go unless you
have some reasons why this won't fly given your resources and
infrastructure.
