Help!!! Cannot reinstall NIC

I un-installed the NIC on server 2003 and everytime I try to re-install
it gives me the error: "An error occurred during the installation of
the device The system cannot find the file specified"

I have tried to install 5 different NIC's all leading to the same
result. I have made sure that all driver files for the devices are
there. I think that it is a registry entry that it is looking for but
I'm not sure which one it is.

Any help would be greatly appreciated!
Thanks,
Kicker
