2 Nic Problem

I'm attempting to set up a win2003 server and have a need
to understand what I consider strange nic behavior.

I have a server mainboard with a built-in nic, to which I
added a PCI nic card.

The Problem: If I plug a cable modem directly into the
built-in nic, everything seems to work. If I plug the
cable modem into the added PCI nic, the cable modem will
not work. Can anyone give me an indication why this should
be?

(I've tried several different nic cards, the result is
always the same.)

How is the 2nd NIC TCP/IP is set up?
Can you post here results of ipconfig /all from the server
(after you have connected the cable modem in to the 2nd (PCI ) NIC ?

It sounds like your cable modem has mapped itself to the
mac address of the your computer's builtin nic. This
happen to me when I install a new wireless router at my
house. It's easy to fix. Your cable modem should have
reset button on the back of it. Plug your cable modem into
the PCI Nic and then hit the reset button. Your cable
modem should then work with the PCI NIC. Then make sure
that PCI Nic is setup like the builtin NIC and everything
should work fine.
