[Samba] 2003 server member of a SMB3 domain

[aurelien sergent]

Hi all

I am facing the following issue :

I 've just installed a fresh windows 2003 server and want to add it to a
samba 3 domain.
netbios is ok on windows, I can log onto the smb server shares... but if I
try to add the 2003 server to the domain it echoes the an error saying that
the PDC for the domain XXX (netbios domain format, not dns) can't be found.

I don't understand why because I have another 2003 server which has joined
the smb domain without any issue some month ago.

client : windows 2003 SP2 (not R2)
server PDC :  Version 3.2.7

global part of smb.conf below :
