Two NIC cards, one network


Tim Lewis


Is there an easy way to setup my windows 2003 server to utilize both NIC
cards in the server on one network? Right now with both of them configured
if I look at the network utilization one is between 15% and 25% all day and
the other sits around 1%. How can I get both of the cards to be used at

Hello Tim,

Depends on your hardware, check for TEAMING software. HP for has teaming
software for all servers.

If it is a desktop PC I expect it would be unlikely that you could use NIC
Teaming which is usually configurable with HP/Dell/IBM server systems.

if you startup a command prompt and do "route print" you should see the
default route going via a preferred interface. To make traffic go
through the other interface e.g to a file server you could try
file server=x.x.x.x
default gw= y.y.y.y
route add x.x.x.x mask y.y.y.y IF 2

where IF 2 would be the second interface card.

This would make traffic towards the file server go via the second interface
and all other traffic go through the 1st.

At least it a theory.

Good Luck and I hope this helps.


If teaming doesn't work you can always create a network bridge. I have done
that with my Windows XP and Windows 2003 Servers.
