This question already has an answer here:

I am a little confused on the proper active directory configurations for the forest root domain. Recommendations call for using corp.example.com or internal.example.com. However, what is the best practice if you own/manage example.com domain? (I own and manage example.com through PowWeb, a web hosting provider).

I want to be able to set up Exchange servers, Web Servers, and FTP servers within the internal (or Corp) network that will be accessible over the internet.

EDIT RELATED QUESTION: Let's say that I decide to use example.com as the root/forest domain in dcpromo.exe. Could I then create a domain corp.example.com, and have the same server that I ran dcpromo on join the corp.example.com domain?

Ultimately, my goal here is to have dcpromo create example.com in its DNS. If I make the root domain in the wizard corp.example.com, it won't create any entries in DNS for example.com.

NOTE: This would be the PRIMARY and FIRST domain controller in the network.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


I linked to the definitive answer for your main question - how do you name your AD domain. For your second question, you cannot have a single domain controller in more than one domain, so you cannot have a single DC be both the DC for the root of your tree, and a subdomain of that tree.

  • Thank you! .... I notice I was voted down. I get negative points if the question was already asked? – Kevin Aug 19 '15 at 22:12
  • Yes, you'll get down voted for not doing research, and that certainly includes here and Google (which will often point here.) – mfinni Aug 19 '15 at 22:14
