[Samba] Expected DNS records for a new ADC?

[Adam Tauno Williams]

I have added a 2008R2 server as an ADC to a domain (S4 4.5.3);  and the
instructions say to verify the DNS records...  what DNS records does
one expect to find?  I think I know but looking in DNS it does not
appear the server created any DNS records relating to being a DC.

No GUID CNAME in _msdcs.micore.us, no SRV records in Default-First-
Site-Name._tcp,...

I have not yet rebooted the server after the promotion.

Replication appears to have started but is not operational.
