Active Directory is completely new to Windows 2000. Even if you’ve used Windows 2000 since its early betas as Windows NT 5.0, you can still benefit from a hands-on refresher of some important Active Directory topics.
The Study Guide in this part includes a lot of step-by-step instructions for performing specific tasks. If you’d like to test yourself, try performing these exercises without looking at the step-by-step instructions. If you can do this, you can feel confident that you are familiar with the day-to-day tasks required to maintain an Active Directory environment.
Install Active Directory by creating a new domain controller for a new tree.
Install Active Directory again, this time creating a new domain controller for the existing tree.
Verify both installations.
