[Samba] Help! WinXP failed to logon via Samba

I got a NT PDC and an Samba server (ver. 2.2.3a) that participates in the domain

The Samba server provide file and print sharing to my private network, but it
authenticates user indirectly via the 'NT_1' PDC.

All the PC clients (Win98) were configured to logon to "workgroup" instead of
domain.This has been always fine until some guies brought in XP Home Edition
(pre-installed in there own new notebook).

Though I had configures these XPs to participate in the 'NT_DOMAIN' workgroup,
they failed to logon to my samba server.

The following is the log file from 'smbd':

  domain_client_validate: unable to validate password for user vcPM1 in domain
DEBBY-NB to Domain controller NT-1. Error was NT_STATUS_NO_SUCH_USER.

The strange thing is that the reported domain name is 'DEBBY-NB' (in fact, this
is the machine name of the client PC)  instead of 'NT_DOMAIN' . Is the XP client
incorrectly tried to logon using this domain name or Samba is not able to
correctly decode the logon request message from XP ?

The following is excerpt from the relevant settings in my samba.conf file.

   protocol = NT1
   printing = bsd
   printcap name = /etc/printcap
   printing = bsd
   load printers = no
   guest account = nobody
   invalid users = root
   security = domain
   password server = NT-1
   workgroup = NT_DOMAIN
   encrypt passwords = yes
   wins support = no
   wins server = NT-1.my-domain
   os level = 64
   domain master = no
   local master = yes
   preferred master = yes
   dns proxy = yes
   wins proxy = no

Can anyone help me?
