If the hardware's OK, Netbeui should work, as long as it's bound to Client for MS Networks and file sharing. Make sure you've got proper shared resources. W2k's default shares (the ones with $ at the end of the name) won't share over a network - they're created for administrative use only. Create new shares, giving them any name you want, and check the box that gives access to everybody. And make sure all computers are in the same workgroup and that computer names are all different.
