1) You did create a machine account (for an NT Workstation or Server)
using the Server Manager on the NT4 Domain?

	Joining the domain will NOT work unless you do.

2) Try:
	smbpasswd -j lister -r cat -Uadministrator
and when prompted type in the domain administrator password.

3) Make sure that the "wins server =" points to a machine
other than your samba server. ie: I guess this is your one of your NT
domain controllers?

4) Last point: Make sure that samba is NOT running when you try to join
the domain, you can safely start it AFTER it has joined the domain.
