Hi Greg,

Thank you for your answer.

Yes, I installed the dns service in the same time I promoted the windows server. When I checked the windows dns, it seemed to be well populated but there maybe some deep record that I missed.

So, when I tried to stop samba windows used it's own dns server.

Is there any known issues with the dns replication between Samba4 and Windows ?

If you haven't moved DNS to the Windows box, then you turn off the
Samba box, you're going to have serious problems.

So, yes, I'd guess it's a DNS problem.
[Here's hoping you still have all your limbs :) ]
