Installing a child domain
As you saw in Installing a replica domain controller, adding a DC to an existing domain is straightforward. So long as prerequisites like DNS are in place, the promotion process is simple.
An AD forest can contain more than one domain. This architecture has some value in terms of delegated control and some reduction in replication traffic. And like creating a replica DC, creating a child domain is simple, as you can see in this recipe.
Best practice calls for a contiguous namespace of domains, where the additional domain is a child of another existing domain. In this recipe, you create a child domain to the Reskit.Org domain you created earlier. You promote the server UKDC1 to be the first DC in a new child domain, UK.Reskit.Org. The steps in this recipe are very similar to those in Installing a replica domain controller.
Getting ready
You run this recipe on UKDC1, a domain-joined server in the Reskit.Org domain on which you have installed...
