Part 3 contains most of the information that relates to the Windows 2000 Active Directory portion of the 70-240 exam. This includes installing and configuring, managing network protocols, configuring desktops, and maintaining security. The chapters in this part primarily use Windows 2000 Server during the various hands-on practices and exercises. However, much of the information presented here is also applicable to Windows 2000 Professional.
Active Directory is the directory service included in Windows 2000 Server. It stores information about objects on a network and makes this information available to users and network administrators. Active Directory gives network users access to permitted resources anywhere on the network using a single logon process. It provides network administrators with an intuitive hierarchical view of the network and a single point of administration for all network objects.
