Have you tried to create a user account (user1) or your name with a password on both the SME server and the W2K box? The user name and password will need to be identical, also remember that the SME user name is case sesitive.
On your Win2K box, make your new user a member of the Administrator group if you want that type of access.
Logout and then login with your new account. You will need to reinstall your printer in the new Windows profile.
I have been running with Windoze 2000 and recently XP with SME5.6 and 6 with no issues with printers and shared folders on the SME boxes.
Enjoy,
