Wont take drivers properly

I have a thinkpad 600e laptop with freebsd and win2k. Freebsd works fine with my 3com lancard and proxim rangelan wifi card. But for win2k, I give it the PROPER drivers and they are even signed but on the device manager they still have the Yellow exclamation mark next to its name.

+Network Adapters
!Proxim Range-Lan-DS

Why wont it take the drivers, I would think that Im giving the wrong drivers, but Im so sure they are right, I got them off the proxim site and another site. Its not that hard to make sure you have the right driver, all you do is match up the device name and OS, and youll find the proper driver. So I dont get why its not working.

Anyways

 

Are you using windows 2000 SP3? Is the card 16 bit or a PC Card?
