samba - Jun 2002 - Joining XP Pro Client to Samba Domain- Was working, not anymore

I have searched for 2 days on the net and can't find an answer.  I am
trying to joing a winXP machine to a domain. I have previously done this
but since a samba upgrade and perhaps other upgrades to the system
(Kernel upgrade?) it no longer works. Previously the auto script
creation process successfully created the machine trust account, but not
anymore. I tried creating the trust account manually and even if I try
to change a machine's ID to an ID that was successfully created when it
was working, but it still gives the same error. I get the result "access
denied" after entering the username, and there is nothing helpful in the
machine specific log's. I think the most helpful messages are in
messages which say:

passdb/pdb_smbpasswd.c:pdb_getsampwrid(1416) 
Jun 26 12:43:32 server smbd[2027]:   unable to open passdb database. 

 
 
I have/am: 
 
*Installed all available registry patches recommended for XP.
*Using root as the user for an account with permissions to join the
domain.
*Using samba 2.2.5
*Redhat 7.2  2.4.9-34
 
 
Can you please help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
