The Samba-Bugzilla – Bug 11908
Windows 7 client cannot join a NT4-style domain when nmbd is started
Last modified: 2016-06-10 16:31:45 UTC
Since the last samba update (4.2.4-3.54.2) windows 7 clients cannot join domain with the error : « La relation d'approbation entre cette station de travail et le domaine principal a échoué » in english : "The trust relationship between this workstation and the primary domain failed".
If the nmbd daemon is stopped, this error does not happen but the network cannot be browsed. The mapped shared can still be accessed.
Is this Samba as an AD DC?
What options do you have in your smb.conf?
Note that use of nmbd on a Samba AD DC has never been officially supported.
My samba was long time running with the same config. The only change was an update. I apologize, to update. This is an error.
I upgrade openSUSE with samba 4.2.4-15.1 and the problem has disappeared. Great job !!!

Finally the bug is always in the last version.
If you do not want to give support, do not create bugs. I had a long time well running samba and after upgrade (because no more supported Linux version), nothing function. Users cannot join the domain, browse the network and connect to share (permission problem).
Is always Linux a valid option ?

Unfortunately bugzilla does not have SLAs. Please contact someone from https://www.samba.org/samba/support/ for paid support if you need someone to just focus on your problem individually.
I have changed anything in my config. I have only upgraded samba. These bug are regression. The problem is not mine it's yours. You break the compatibility, so you must repair.
Windows 7 doesn't support joining NT4-style domain controllers anymore, see
There are some Windows hacks to still be able to join described here:
However we are not responsible for Microsoft products.
I repeat ; I does not change anything except samba upgrade.
OK ! No support ?
I solve myself the problems by upgrading to samba 3.
