Samba on Mac OS X 10.2 Client as a PDC for Win2K

The subject pretty much explains what I am trying to do. I am trying to set up my Beige G3 as a PDC for a few Windows machines in my house. I've edited the smb.conf and ran through the steps for adding a machine and editing the information in NetInfo. Did the smbpasswd command stuff. But here's where I'm running into trouble. When I try to join the domain on the Windows machine when it asks for a login, if I type root and the root password it says "Logon failure: unknown user name or bad password."...then if I try with my normal admin user account boberito, it gives me a different error "the account used is a computer account. Use your global user account or local user account to access this server" Any ideas on how to fix that or enable root so that it sees it and knows it? Or is this whole thing not possible to do on 10.2 client. I didn't do any of the ldap stuff because of obviously not being on 10.2 Server. If someone could email me and give me some assistance I'd greatly apprciate it. Thanks, Bob boberito@mac.com
