Home or Small Office Networking

I’m presently running NetBEUI for a home network w/o using a server. It isn’t very efficient. I would like to run the MS Home or Small Office Networking, but 2 of the 5 computers are running WIN 2K Pro. Has anyone come up with a way to run this on a WIN 2K system? I’d prefer not to upgrade the 2K systems as I need that O/S for testing.
