samba - Sep 2001 - Win2K Joing Samba Domain Issue

Have searched hi & low but can't find an answer in the archives, from M$
or anywhere.  Have been working this issue on and off for the past 2 weeks.

I'm having problems getting a Win2K Pro PC (the only one I have) to join the
Samba domain.  The PC was previously setup as a member of a workgroup and, in
fact, will join Samba as a workgroup but not as a domain.  When I try to change
to the domain, I get a dialog box that says:

"Enter the name and password of an account with permission to join the
domain."

I enter my name and password and get the following:

"The following error occurred attempting to join the domain STGroup.  No
mapping between account names and security Ids was done."

A user can search for the server (SMB1), double-click on it and login just fine
but the script doesn't run.  Since all the Win9x and WinNT PCs are logging
in as domain members and are running the script okay, I assume that you have to
login to a domain to get the script to run.  True???

What am I doing wrong???

Using RedHat 7.1, Samba 2.2.1a.  The client PC is Win2K, SP2.  The PC name is
Win2K.  I manually created the trust account in passwd for Win2K$ and then added
to smbpasswd with smbpasswd -a -m Win2K.

Attached below is my smb.conf.

Thanks for any help,
