Designating Tree Root Domains
Once you’ve determined the number of trees in each forest for your organization, you should determine which domain will serve as the tree root domain for each tree. The tree root domain is the highest-level domain in the tree; child and grandchild domains are arranged under it. Typically, the domain you select should be the one that is most critical to the operation of the tree. A tree root domain can also be the forest root domain, as shown in Figure 4-6.
When creating additional trees, you use the Active Directory Installation Wizard. To create an additional tree, complete the following steps:
1.Restart your computer and log on as Administrator.
2.Click Start and then click Run. In the Run dialog box, type dcpromo in the Run box and click OK.
3.On the Welcome To The Active Directory Installation Wizard page, click Next.
4.On the Operating System Compatibility page, click Next.
