Hello Matthieu,

I am working in with VMs, so it's very easy to deploy and test systems. I
shutdown the Samba server and provisioned a 2008R2 server using the same
domain name "testdom.com". When I join another 2008R2 server to this
domain, it correctly detects one authoritative DNS server. Please let me
know if you have any advice. I am surprised that no one has reported this
before - I would assume most AD root domains are not provisioned as
subdomain. We will be using a subdomain and I only stumbled on this issue
trying to resolve the demotion issue, however I am happy help with further

I have opened a bug regarding the problem I am seeing when demoting a
Windows Server.
