Hi all,

I've a SAMBA4 AD DC primary controller, another server joined as DC too, 
all worked pretty good since this morning....

This morning, I need to join a lot of workstations to the domain, I 
begin on the first one and get an error message 'This operation must be 
done on the primary domain controller'.... strange. I go on my first PDC 
checking network, DNS (dbcheck returns no error).... nothing, I do a 
'smbclient -L localhost -U Administrator' and I get an 
'INVALID_SERVER_STATE error message', I do the same on my other PDC : 
the command returns valid answer.

I've restarted the 'samba' daemon on my first PDC and all works now....

I've 2 questions :

* Why my first PDC becomes magically in an invalid state (without any 
modification) ? (and what seems INVALID_STATE ?)
* Why my second PDC doesn't respond when I try to join my workstation 
and my first PDC was in an invalid state ?

I hope this 'invalid state' wasn't too often 'cause it would be really 
inconvenient when all users will come back from holidays.

Best Regards,
