Overview

Features of Active Directory in Windows Server 2003.

Creating a domain by installing Active Directory.

Domains

A domain is: A container for every element on a network. A security boundary between the domain and

the rest of the environment.

by Rashid Khan

Domains

The domain acts as a container for all network objects and as a security boundary.

by Rashid Khan

Trees

Trees are a hierarchy of related domains.All domains in a tree possess a two-way,

transitive trust between them.

by Rashid Khan

Trees

A tree consists of domains that share a contiguous namespace.

by Rashid Khan

Trees

The domains that make up a tree must share a common schema and the parent/child relationships that describe classes of network objects in Active Directory.

Since domains in a tree are separate, they do not directly replicate each other’s Active Directory data stores.

A domain controller (DC) acts as the global catalog (GC).

by Rashid Khan

Forests

Forests: Are made up of trees. Contain a disjointed namespace between the

domains of a tree and the domains of another tree.

Share a common schema and a common GC.

by Rashid Khan

Forests

A forest consists of domains in a disjointed namespace.

by Rashid Khan

Organizational Units and Sites

Organizational units (OUs)Sites

by Rashid Khan

Organizational Units

Organizational units: Are logical network structures. Are used to subdivide a domain into

manageable parts without creating new domains.

Enable administrators to group user accounts, user groups, computer accounts, and other Active Directory objects.

by Rashid Khan

Sites

Sites: Address the physical structure of a network. Require the network to be divided into subnets. Enable customization of the multimaster

replication process between DCs.

Features of Active Directory in Windows Server 2003 Basic benefits of Active Directory.New features of Active Directory.

Basic Benefits of Active Directory

Simplified managementStrong securityInteroperability

by Rashid Khan

Simplified Management

Active Directory simplifies management by: Enabling administrators to efficiently administer

the centrally-located network objects and structures.

Helping users to access the shared resources on the network.

Helping to publish shared folders so that users can easily locate the folders on the network.

by Rashid Khan

Strong Security

Active Directory strengthens security by: Selectively granting permissions to users to

access specific resources. Allowing these permissions to be applied to

users or groups, through a one-time authentication of the user at logon.

by Rashid Khan

Interoperability

Active Directory enables interoperability by enabling users to share its resources with other applications.

It can also be used to adjust the performance of hardware components to the needs of the organization.

by Rashid Khan

New Features of Active Directory

Improved user interface.Group Policy Management Console

(GPMC).Renaming domains.

by Rashid Khan

Improved User Interface

Windows Server 2003 version of Active Directory: Allows users to drag and drop Active Directory

objects. Allows administrators to select and edit multiple

objects at a time.

by Rashid Khan

Group Policy Management Console (GPMC) Group Policy allows administrators to control

settings that affect user accounts and computers.

Policies can be applied to domains, sites, and organizational units.

The GPMC utility allows administrators to easily edit policies across multiple OUs, domains, or sites.

It also enables to back up and restore policies.

by Rashid Khan

Renaming Domains

Domains in Windows Server 2003 can be renamed without demoting them.

Also, renaming a domain does not affect the logical structures of a domain, tree, and forest.

level.

Plan the Active Directory Installation

Domain name.Folder locations.Domain Name System (DNS) and support

for pre-Windows 2000 Server operating system.

Restore Mode administrator password.

by Rashid Khan

Domain Name

Should be similar to Internet DNS names, and should be registered.

Should be short, which makes it easy to remember and type.

by Rashid Khan

Folder Locations

The Active Directory database and the log files are stored in the NTDS subfolder of the WINDOWS folder.

The SYSVOL folder contains the information that is replicated between DCs.

by Rashid Khan

DNS and Support for Pre-Windows 2000 Server Operating System It is recommended to install and configure

DNS service before installing Active Directory.

The users need to specify whether or not Active Directory installation program should support older server operating systems during the installation.

by Rashid Khan

Restore Mode Administrator Password If the Active Directory data store is

corrupted, Restore Mode can be used to fix the problem.

The Restore Mode administrator password is required to use the Restore Mode.

Raise the Domain and ForestFunctional Level The domain functional level must be raised to

the Windows Server 2003 level to use the new domain features.

Once the domain functional level has been raised, it cannot be lowered.

Changes made to the forest functional level are irreversible.

Forest functional levels cannot be raised until the domain functional level has also been sufficiently raised to support the change.

Summary

A domain is the container for elements on a network.

A tree is made up of a hierarchy of related domains.

A forest is made up of trees.Forests share a common schema and a GC.Organizational units are used to subdivide a

single domain into manageable parts.

by Rashid Khan

Summary

Sites address the physical structure of a network.

Some of the benefits of Active Directory are simplified management, strong security, and interoperability.

Some of the new features of Active Directory are improved user interface, Group Policy Management Console (GPMC), and the ability to rename domains.

by Rashid Khan

Summary

Installing Active Directory makes the network server a DC.

Planning the installation of Active Directory includes choosing a domain name and the folder locations, and determining whether the DNS is installed or configured properly.

Planning the installation of Active Directory also includes determining whether the Active Directory should support older versions of the operating system.
