My friends:

My samba file server have been working well for a year up to yesterday, 
when It stopped suddently. It was on a debian vz container  (Proxmox 
3.4). The first problem was a root user with quota  exceeded and I 
couldn't get domain users using "wbinfo -u". I got out quota 
restrictions from the container but I can't still use wbinfo. Then, when 
I try to use "net ads join -U administrator" to join to the domain It 

root at samba1:/# net ads join -U administrator
root at samba1:/# Host is not configured as a member server.
Invalid configuration.  Exiting....
Failed to join domain: This operation is only allowed for the PDC of the 

And I usually do that when some time the file server loses the join. 
Besides, I can do that from other samba file server. So, the problem 
seems to be out of domain controller.

I really don't know what to do!

Any idea?
