samba - Feb 2004 - adding XP Pro to Samba 2.2.8a Domain Controller Problem.

All,

Little problem here,
we are running Samba 2.2.8a (smb.conf attached) on tru64, UNIX accounts 
& Passwords are distributed via NIS from another site (so the samba add 
user/machine scripts won't work)I've applied the RequireSignOrSeal patch
& changed the settings as recomended at http://www.wlug.org.nz/SambaAsPDC

When attempting to join the domain (using the user domain\root) the 
Windows Box gives an error "The specified Network Password is not 
Correct" (the password is correct) & the log on Samba shows

[2004/02/06 16:04:35, 0] smbd/service.c:make_connection(563)
   Can't become connected user!
[2004/02/06 16:04:49, 0] smbd/service.c:make_connection(563)
   Can't become connected user!
[2004/02/06 16:04:50, 0] smbd/service.c:make_connection(563)
   Can't become connected user!

Any thoughts?
