I have to beg the question WHY? If it's a server he doesn't need a gaming card in there - the onboard should suffice.
If he is gaming on a server OS for some deranged reason, he can pickup a Geforce2 MX used for $20 which will FAR outperform the Voodoo5.
ANYWAY if he's a glutton for punishment, the problem probably has to do with the onboard card. It has to be properly disabled. There should be a setting in BIOS that disables it - some mobos might have a jumper instead.
There might also be a setting in BIOS that lets you select whether it initialized PCI or AGP for video first. The onboard is an AGP. If the V5 is a PCI he'll need to change that setting.
Sometimes you just can't get a mobo with onboard video to recognize an add-on card - common problem. Either it works or it doesn't.
There were never any official Voodoo drivers released for Win2K that worked worth a dang. The only luck he'll have is with hacked drivers. He should find some here:

HOWEVER I wouldn't be suprised if they didn't work properly under 2K Server - they're designed for 2K Pro and there ARE differences.
MY ADVISE TO YOUR FRIEND: Use the Voodoo5 for a doorstop. 3Dfx is dead.... LONG since dead... get over it and move on with your life.
