NIC's not being recognized when 2 NIC's in 1 Win03 server

I would like to have a public (cable modem & using router) external network
and a private local network (crossover utp) between my 2 pc's
The box with the 2 nic's is Win03 and the client box is a WinXP Pro box.
Windows 2003 will not recognize the second nic correctly. Hardware is IDed
as a second rlt8139 nic when in fact it is a DLink. There is only 1 rlt8139
nic installed in the win03 server. the other nic is a DLink. How do I get
Win03 to properly identify and distinguish these NIC's?
I want to run NAT.
