samba - Oct 2002 - w2k machine fails to join Samba PDC domain

Hi,

I have trouble to join a new w2k machine with SP3 and pre-SP4 hotfix into
our Samba PDC (2.2.5).  It works in a machine which as only SP3. I haven't
yet tried remove the hotfix and it will be my next step.  I have turned
log level to 10 but I didn't see any error message on Samba side.  Any
suggest
which I can debug this problem.

Thanks,

-Calvin
