Module 1: Introduction to Managing a Windows 2000 Network 1 Overview ! Overview of Active Directory ! Active Directory Logical Structure ! Active Directory Physical Structure ! Managing a Windows 2000 Network In a Microsoft ® Windows ® 2000 network, Active Directory ™ directory service provides the structure and functions for organizing, managing, and controlling network resources. To implement and administer a Windows 2000 network, you must understand the purpose and structure of Active Directory. Active Directory also provides the capability to centrally manage your Windows 2000 network. This capability means that you can centrally store information about the enterprise, and administrators can manage the network from a single location. Active Directory supports the delegation of administrative control over Active Directory objects. This delegation enables administrators to assign specific administrative permissions for objects, such as user or computer accounts, to other users and administrators. After completing this module, you will be able to: ! Describe the function of Active Directory. ! Describe the logical structure of Active Directory. ! Describe the physical structure of Active Directory. ! Describe the methods for administering a Windows 2000 network. Topic Objective To provide an overview of the module topics and objectives. Lead-in In this module, you will learn about managing a Windows 2000 network. 2 Module 1: Introduction to Managing a Windows 2000 Network " "" " Overview of Active Directory ! What Is Active Directory? ! Active Directory Support for Client Computers ! Active Directory Objects ! Active Directory Schema ! Lightweight Directory Access Protocol (LDAP) Active Directory stores information about resources on the entire network and makes it easy for users to locate, manage, and use these resources. Active Directory is made up of multiple components. You must understand the components and how to use them to administer Active Directory. Topic Objective To introduce Active Directory. Lead-in Active Directory stores information about resources on the entire network. Module 1: Introduction to Managing a Windows 2000 Network 3 What Is Active Directory? Directory Service Functionality Directory Service Directory Service Functionality Functionality ! Organize ! Manage ! Control ! Organize ! Manage ! Control Resources Resources Centralized Management Centralized Management Centralized Management ! Single point of administration ! Full user access to directory resources by a single logon ! Single point of administration ! Full user access to directory resources by a single logon Active Directory is the directory service in a Windows 2000 network. A directory service is a network service that stores information about network resources and makes the resources accessible to users and applications. Directory services provide a consistent way to name, describe, locate, access, manage, and secure information about these resources. Directory Service Functionality Active Directory provides directory service functionality, including a means of centrally organizing, managing, and controlling access to network resources. Active Directory makes the physical network topology and protocols transparent, so that a user on a network can gain access to any resource without knowing where the resource is or how it is physically connected to the network. An example of this type of resource would be a printer. Active Directory is organized into sections that permit storage for a very large number of objects. As a result, Active Directory can expand as an organization grows, so that an organization that has a single server with a few hundred objects can grow to having thousands of servers and millions of objects. Centralized Management A server running Windows 2000 stores system configuration, user profiles, and application information in Active Directory. Combined with Group Policy, Active Directory enables administrators to manage distributed desktops, network services, and applications from a central location while using a consistent management interface. Active Directory also provides centralized control of access to network resources by allowing users to log on only once to gain full access to resources throughout Active Directory. Topic Objective To illustrate the purpose of Active Directory as a network directory service. Lead-in Active Directory stores information about resources in a Windows 2000 network and makes the resources accessible to users and applications. Key Points Active Directory provides directory service functionality, including a means of centrally organizing, managing, and controlling access to network resources. Active Directory enables administrators to manage distributed desktops, network services, and applications from a central location while using a consistent management interface. 4 Module 1: Introduction to Managing a Windows 2000 Network Multimedia: Concepts of Active Directory in Windows 2000 This multimedia presentation describes basic Active Directory concepts, such as organizational units, trees, forests, Domain Name System (DNS) naming conventions, and sites.
