[Samba] Windows vista ultimate samba 3.0.31

[Daniel Müller]

Hello to all

I have setup samba 3.0.31 as PDC successful with xp clients.
Now I have a vista ultimate pc which I cannot join to the domain.
The error message when I try to join to the domain is:
The Domain is unavailable or the connection could not be established.

What I've done so far:

Run secpol.msc --> Local Plicies-->Security Options -->Lan Manager
authentication level-->changed it to:
LM and NTLM- use NTLMV2 session security if negotiated.

Had someone did the trick??
