samba - Oct 2009 - samba 3.0.33: Can't change computer names in a domain

Hello! I saw there is a lot of people with the same problem that mine,
but they are using recent versions of samba.

I am using 3.0.33 in a CentOS 5.3 server wich is supposed to be realy
stable and tested.

At server side, machine trust account gets renamed both in /etc/passwd
and in samba database.

But at client side, the windows box shows an error and keeps his old
name.

This is what smbd.log shows:
