When you install the Windows 2000 Server operating system, you cannot make the server a domain controller during installation as you can with NT.
Instead, you must run the DCPROMO utility. You can do this immediately or at any time after installation. DCPROMO invokes the Installation Wizard, which allows you to choose the role of the domain controller and installs Active Directory on the computer. The Configure Your Server utility that displays immediately after installation contains instructions on using DCPROMO.
In the next lesson, you'll begin to learn this installation process with an overview of the Installation Wizard.
