Version: 2:4.9.5+dfsg-5.  Yes, internal DNS.

Yes, joined to AD-Domain where the DC was Windows Server 2003. Roles 
were transferred except forestdns and domaindns.  These did not transfer 
on first attempt but then they appeared to not have an owner so I seized 
both of them.  The Server 2003 machine is still active in the domain.

I used these settings last week but haven't rebooted.
