How to Install Active Directory and DNS
The Active Directory Installation Wizard helps simplify the process of configuring a domain controller that is running on Windows Server 2003. You do not have to install Domain Name System (DNS) as a separate step because the Active Directory Installation Wizard installs it as part of its operation. This is not true for additional domain controllers.
