Further investigation:

When I query the WINS server with winbind:
$ wbinfo -N XXXXX
the query goes to the WINS Server asking for XXXXXX          <20> (Server
Service)

If I query the WINS from a windows machine:
c:\>ping XXXXX
the query goes to the WINS Server asking for XXXXXX         <00>
(Workstation/Redirector)
And it always gets and answer from the WINS server.


Looking at the WINS database in the server, I can see that only some
machines  (Servers??) have a <20> entry.

The end result is that samba cannot resolve successfully machine names.
Anybody connecting from any machine samba is unable to resolve, will
connect to my Linux servers as nobody!!!

Does anybody knows what's wrong here?

Thanks for your help in advance.
