  2. Agenda • Chapter 1: Overview of Active Directory Domain Services • Quiz • Exercise

  3. What is AD? • Centralized authentication service • Directory service • X.500 • Uses a hierarchical approach in which objects are organized in a similar way to the files and folders on a hard drive. • Lightweight Directory Access Protocol (LDAP) • Slim-down version of X.500 modified to run over the TCP/IP network.

  4. Active Directory in Server 2008 • Active Directory Domain Services (AD DS) • It’s an AD on Windows server 2008 • Active Directory Lightweight Directory Services (AD LDS) • A simpler version of directory services that integrate with ADDS to provide directory services

  5. Domain Controller (DC) • A server that stores the Active Directory database and authenticates users with the network during logon. • Information are stored in a file called ntds.dit • Multimaster database • Replication • Outbound replication – sender • Inbound replication – receiver

  6. Major benefits of ADDS • Centralized resource and security administration • Single logon for access to global resources • Fault tolerance and redundancy • Simplified resource location

  7. Functional Levels • Provide interoperability with prior versions • Windows Server 2000, Windows Server 2003, EXCEPT Windows NT • When DC installed: • AD Users and Computers • AD Domains and Trusts • AD Sites and Services • ADSI Edit (Service Interfaces)

  8. Fault Tolerance and Redundancy • Active Directory uses a multimaster domain controller design. • Changes made on one domain controller are replicated to all other domain controllers in the environment. • It is recommended to have two or more domain controllers for each domain.

  9. Read-Only Domain Controller (RODC) • A domain controller that contains a copy of the ntds.dit file • cannot be modified • does not replicate its changes to other domain controllers with Active Directory.

  10. Simplifying Resource Location • Allows file and print resources to be published within Active Directory. Such as: • Shared folders • Printers

  11. Active Directory Components • Forests • One or more domain trees, with each tree having its own unique name space. • Domain trees • One or more domains with contiguous name space. • Domains • A logical unit of computers and network resources that defines a security boundary. • Organization Units (Ous)

  12. Forests • Naming contexts (NCs) • To improve the efficiency of the AD – Multiple partitions • Schema NC • Rules and definitions that are used for creating and modifying object classes and attributes within AD • Configuration NC • Information regarding the physical topology of the networks, as well as other configuration data that must be replicated • Both NCs are replicated forest-wide and stored in the NTDS.dit file on every DC in a forest

  13. Domain NC • Consists of user, computer, and other resource information

  14. Deploying Domain Trees • Parent-child relationship • Every domain has Domain NC • Users, groups, computers, etc. • Lucernepublishers.com can considered as Forest root domain

  15. Working with OUs • A logical grouping of resources that have similar security or administrative guidelines • You can delegate administrative rights to supervisor or manager • Users • Groups • Contacts • See more objects on Page 7 • Application partition • To specify/manage the scope of replication

  16. Schema • Each object is defined within the AD schema • Object classes • Attributes • Common attributes are as follows: • Unique name • Globally unique identifier (GUID) • Required object attributes • Optional object attributes

  17. AD Sites and Subnets • Sites are used to optimize the replication of AD information • Intersite replication takes place at regularly scheduled intervals • Knowledge Consistency Checker (KCC) • Use to maintain the replication topology

  18. AD Naming Standards (LDAP) • LDAP refers to an object using its distinguished name (DN) • Example: • cn=JSmith, ou=sales, dc=lucernepublishing, dc=com

  19. Domain Name System (DNS) • Resource records : • SRV records • A record in DNS that points to any resource in your site or domian • Locator service for LDAP/Domain controllers services • Host (A) – Host name to IP. • Pointer (PTR) – IP to Host name.

  20. Domain Functional Levels • Higher levels of functional level will not allow older versions of Windows to function but will add additional functionality or features. • Raising functional level is a one-way process.

  21. Domain Functional Levels • Windows 2000 native • Windows Server 2003 • Windows Server 2008 • Read-Only Domain Controller (RODC) • See Page 12 – 13 for more detailed

  22. Forest Functional Levels • Same as Domain Functional levels. Forest functional level applied too all domains in that forest • To raise the forest functional level, all domains in that forest has to be raised to the same level first • See Table 1-3 on Page 15

  23. Trust Relationships • Two-way transitive trusts • Transitive trust • A -> B -> C, then A -> C • Shortcut trust • If the links in between are slows, you can create a shortcut trust. It will be one-way trust • External trust • A one-way trust to connect to another domain in a separate forest

  24. Trust Relationships (2) • Cross-forest trust • Required Windows Server 2003 forest functional level • Can be one-way or two-way relationship • It is a transitive trust

  25. Assignment • Fill in the blank • 1-10 • Multiple Choice • 1-10 • Online Lab 1
