[Samba] smb.conf 3.0.7 -> 3.0.23c domain master problem

[Bgs]

  Hi all,


We have an old 3.0.7 samba running as PDC. As we have problems with XP64 
clients accessing the domain, I compiled a 3.0.23c and copied the 
smb.conf. Some of the client work well with the new Samba, but most of 
them do not. Was there any relevant change in the smb.conf part between 
the two versions?

Thanks
Bgs
