Start by listing your system specs, then listing what you have installed update wise on the Win2k system.
Things you will need for sure:
Win2k Service Pack 2
Win2k DirectX 8.0
Get SP2 first and foremost. There are some nasty internet viruses running around that cause considerable problems if you do not. Then get every security update known to man. The best way to find these programs is to click on "start" then "Windows Update". Follow the instructions from there.
