27 Guide to MCSE 70-270, 70-29027 Computer Accounts Computers running Windows NT, Windows 2000, Windows XP, or Windows Server 2003 assigned computer accounts as part of joining a domain –Provides method for authenticating computers that are members of a domain and auditing access to network resources In Active Directory, computer accounts represented as computer objects –Can be viewed using administrative tools Such as Active Directory Users and Computers

28 Guide to MCSE 70-270, 70-29028 Introduction to Windows Server 2003 Active Directory Directory service: Provides central means of storing, managing, and accessing information about network objects belonging to domain(s) Active Directory: Native directory service included with Windows Server 2003 –Central point for storing, organizing, managing, and controlling network objects –Single point of administration of objects and Active Directory published resources –Logon and authentication services for users –Delegation of administration

29 Guide to MCSE 70-270, 70-29029 Active Directory Time Synchronization When change transaction made to an Active Directory domain controller, it is time stamped and sent to other domain controllers –Domain controllers must synchronize internal clocks Network Time Protocol (NTP)

30 Guide to MCSE 70-270, 70-29030 Domain Name Services Active Directory uses Domain Name Service (DNS) to maintain domain-naming structures and locate network resources –Active Directory names must follow standard DNS naming conventions

31 Guide to MCSE 70-270, 70-29031 Active Directory Objects Object: Represents network resources –i.e., users, groups, computers, and printers When object created in Active Directory, attributes assigned to supply information about object Can perform search of specific attributes related to objects

32 Guide to MCSE 70-270, 70-29032 Active Directory Objects (continued) Figure 1-6: Creating a new user object

33 Guide to MCSE 70-270, 70-29033 Active Directory Schema Defines objects and attributes for entire Active Directory structure –One schema for an Active Directory implementation Replicated among all domain controllers on network Consists of two main definitions: –Object classes: Types of objects able to be created –Attributes: Describe the object Created and stored separately in schema Can be used with multiple object classes

34 Guide to MCSE 70-270, 70-29034 Active Directory Logical Structure and Components Logical components that make up an Active Directory structure: –Domains and organizational units –Trees and forests –Global catalog

35 Guide to MCSE 70-270, 70-29035 Domains and Organizational Units Organizational unit (OU): Logical container for organizing objects in a single domain –Store users, groups, computers, and other OUs –Easier to locate and manage Active Directory objects –Ability to apply group policy settings to define more advanced features –Ability to delegate administrative control over OUs

36 Guide to MCSE 70-270, 70-29036 Domains and Organizational Units (continued) Figure 1-8: An Active Directory domain and OU structure

37 Guide to MCSE 70-270, 70-29037 Trees and Forests May need multiple domains within network Forest root domain: First Active Directory domain created in an organization –When multiple domains needed, connected to forest root to form single tree or multiple trees Tree: Hierarchical collection of domains –Share contiguous DNS namespace Transitive trust: All trusted domains implicitly trust one another Forest: Collection of trees that do not share contiguous DNS naming structure

38 Guide to MCSE 70-270, 70-29038 Trees and Forests (continued) Figure 1-9: The Dovercorp.net domain tree

39 Guide to MCSE 70-270, 70-29039 Trees and Forests (continued) Figure 1-10: Creating an Active Directory forest

40 Guide to MCSE 70-270, 70-29040 Global Catalog Index and partial replica of objects and attributes most often used throughout the Active Directory structure Used primarily to: –Enable users to find Active Directory information –Provide universal group membership information for logging on to network –Supply authentication services when users from other domains log on with User Principal Name (UPN) –Respond to directory lookup requests

41 Guide to MCSE 70-270, 70-29041 Active Directory Communication Standards Lightweight Directory Access Protocol (LDAP): Used to query or update Active Directory database directly –Follows specific naming convention Distinguished name: Unique for every object –Domain component (DC) –Common name (CN) Relative distinguished name (RDN): Portion of DN that uniquely identifies the object in the container

42 Guide to MCSE 70-270, 70-29042 Active Directory Physical Structure Relates to actual connectivity of physical network –Must ensure that modifications to Active Directory database replicated quickly between domain controllers –Must design topology so that replication doesn’t saturate available network bandwidth Active Directory site: Combination of one or more Internet Protocol (IP) subnets linked by high-speed connection Site link: Configurable object –Represents connection between sites

43 Guide to MCSE 70-270, 70-29043 Active Directory Physical Structure (continued) Figure 1-11: The site structure of Dovercorp.net

44 Guide to MCSE 70-270, 70-29044 Setting Up Active Directory: Plan the Domain Structure Define domains needed –Reasons for implementing multiple domains: Delegation of administrative tasks Geographical location Security High number of objects When a Windows Server 2003 computer promoted to domain controller, given options to add server to existing domain or to create new domain

45 Guide to MCSE 70-270, 70-29045 Setting Up Active Directory: Plan the Domain Structure (continued) Figure 1-12: Options for creating a new domain

46 Guide to MCSE 70-270, 70-29046 Setting Up Active Directory: Plan the Namespace Active Directory uses hierarchical domain-based name structure to locate network computers Active Directory uses NetBIOS names for backward compatibility with older systems –NetBIOS names not based on hierarchical system of domains Public namespace: Allows users to access network resources from any location Private namespace: Contained only on internal DNS servers

47 Guide to MCSE 70-270, 70-29047 Setting Up Active Directory: Plan the Namespace (continued) Figure 1-13: Configure TCP/IP settings for an Active Directory domain controller

48 Guide to MCSE 70-270, 70-29048 Activity 1-3: Configuring TCP/IP on a Windows Server 2003 Computer Objective: Configure the IP address of DNS on a Windows Server 2003 computer –Via network connections properties

49 Guide to MCSE 70-270, 70-29049 Installing Active Directory Installation of Active Directory performed by promoting one or more servers to domain controllers –Should select most capable server as first domain controller –Servers to be promoted should be assigned fixed IP addresses and appropriate names Promotion involves using Dcpromo to install Active Directory service on computer

50 Guide to MCSE 70-270, 70-29050 Activity 1-4: Installing Active Directory Objective: Use Dcpromo to install Active Directory and DNS on your Windows Server 2003 computer –Promoting first server on network to a domain controller installs Active Directory service on the selected server and creates the Active Directory forest root for the network

51 Guide to MCSE 70-270, 70-29051 Summary Windows Server 2003 and Windows XP Professional offer a distinct operating environment The Windows XP family of operating systems is available in several editions Windows Server 2003 is available in four editions A workgroup model is characterized by decentralized authentication and administration A domain model provides centralized authentication and administration

52 Guide to MCSE 70-270, 70-29052 Summary (continued) Active Directory is the native directory service for Windows Server 2003 operating systems The logical components of Active Directory include domains, organizational units, trees, forests, and the global catalog The physical components of Active Directory include domain controllers and sites The process of promoting a Windows Server 2003 system to a domain controller involves using Dcpromo to install Active Directory services on the server

53 Guide to MCSE 70-270, 70-29053 Summary (continued) Although Active Directory uses both DNS and NetBIOS to name domains, DNS is the primary naming system Before promoting a server to an Active Directory domain controller, you should plan the domain and namespace structure and identify the DNS server to be used
