Can I get a best practice recommendation with regard to adding a child domain DC in server 2012R2?
In order to fully DCPROMO I assume that the child server needs the parent domain DC's IP as it's primary DNS entry? (even if this will change afterwards) otherwise it won't be able to contact the existing DC?
Should I create a new site in sites and services on the parent DC prior to DCPROMO of the child server? Or am I correct in thinking that in 2012 this is taken care of during the AD DS services during DCPROMO?
Thanks in advance
