A query is a specific request made by a user to the global catalog in order to retrieve, modify, or delete Active Directory data. The following steps, illustrated in Figure 1-9, describe the query process: 1. The client queries its DNS server for the location of the global catalog server. 2. The DNS server searches for the global catalog server location and returns the IP address of the domain controller designated as the global catalog server. 3. The client queries the IP address of the domain controller designated as the global catalog server. The query is sent to port 3268 on the domain controller; standard Active Directory queries are sent to port 389. 4. The global catalog server processes the query. If the global catalog contains the attribute of the object being searched for, the global catalog server provides a response to the client. If the global catalog does not contain the attribute of the object being searched for, the query is referred to Active Directory. You can configure any domain controller or designate additional domain controllers as global catalog servers. When considering which domain controllers to designate as glo bal catalog servers, base your decision on the ability of your network structure to han dle replication and query traffic.

As an administrator, you must place global catalog servers in sites to provide quick responses to user inquiries, as well as redundancy. See Lesson 3, Planning the Active Directory Infrastructure Design, to learn the basics of designing global catalog server placement. See 5, Configuring Sites and Managing Replication, for details about configuring global catalog servers.

Lesson Review
The following questions are intended to reinforce key information presented in this lesson. If you are unable to answer a question, review the lesson and then try the ques tion again. Answers to the questions can be found in the Questions and Answers section at the end of this chapter. 1. How is a directory service different from a directory
2. How is Active Directory scalable

Introduction to Active Directory
3. What is multimaster replication
4. Name the Active Directory components used to represent an organization s logical structure.
5. Name the physical components of Active Directory.
6. What is the function of the global catalog
Lesson Summary
A directory service stores all the information needed to use and manage system objects in a centralized location, simplifying the process of locating and managing these resources. Data stored in Active Directory is organized into objects, which have attributes. The Active Directory schema defines objects that can be stored in Active Directory. Schema classes and attributes define the Active Directory schema. The logical structures in an organization are represented by the following Active Directory components: domains, OUs, trees, and forests. The physical components of Active Directory are sites and domain controllers. The global catalog is the central repository of information about objects in a tree or forest.

Lesson 2: Understanding Active Directory Concepts and Administration Tasks
In the Windows Server 2003 family and Active Directory, there are several new con cepts and some changes to the concepts used in Windows NT. These concepts include replication, trust relationships, change and configuration management, group policies, DNS, and object naming. It is important that you understand the meaning of these con cepts as they apply to Active Directory. In addition, you should also familiarize yourself with the Active Directory administration tasks, which correspond to the chapters in this training kit.
After this lesson, you will be able to
Explain Active Directory replication Explain the security relationships between domains in a tree (trusts) Explain the components of change and configuration management Explain the purpose and function of Group Policy Describe how DNS is used by Active Directory Describe how objects are named in Active Directory Describe the tasks required for Active Directory administration
Estimated lesson time: 20 minutes
Replication
Users and services should be able to access directory information at any time from any computer in the domain tree or forest. Replication ensures that changes to a domain controller are reflected in all domain controllers within a domain. Directory informa tion is replicated to domain controllers both within and among sites.
