    Study Notes

    Active Directory Domain Services

    • Active Directory is a Microsoft service that provides centralized authentication and authorization to network resources.
    • Active Directory is used in business environments to simplify user management, control access to data and enforce company security policies.

    The Role of a Directory Service

    • A network directory service stores information about a computer network and offers features for retrieving and managing that information.
    • Directory services can be used to find resources.

    Windows Active Directory

    • Active Directory features:
      • Hierarchical organization.
      • Centralized but distributed database.
      • Scalability
      • Security
      • Flexibility
      • Policy-based administration

    Active Directory Structure

    • Physical structure: Consists of sites and servers configured as domain controllers
    • Logical structure: The directory service’s look and feel after the running organization.

    What's Inside Active Directory

    • Explore Active Directory using the Active Directory Administrative Center (ADAC) and Active Directory Users and Computers management console
    • ADAC allows you to perform the following tasks:
      • Create and manage users, group, and computer accounts.
      • Manage OUs.
      • Connect to other domain controllers in the same or a different domain.
      • Change the domain’s functional level and enable the AD Recycle Bin.

    The Active Directory Schema

    • Object: A grouping of information that describes a network resource.
    • Schema: Defines the type, organization, and structure of data stored in the AD database.
    • Schema Classes: Define the types of objects that can be stored in Active Directory.
    • Schema Attributes: Define the type of information stored in each object
    • Attribute value: Information stored in each attribute.

    Active Directory Container Objects

    • A container object contains other objects.
    • Container objects are used to organize and manage users and resources on the network.
    • Container Objects can also act as administrative and security boundaries.
    • Three types of container objects:
      • Organizational Units
      • Folder objects
      • Domain objects

    Organizational Units

    • OUs are a primary container object for organising and managing resources in a domain
    • OUs can organise multiple objects into logical administrative groups that can be configured with specific policies relevant to that group
    • Authority of an OU can be delegated.

    Working with Forests, Trees, and Domains

    • Smaller organizations most likely focus on OUs and their child objects, whereas larger organizations might require an AD structure composed of several domains, multiple trees, and even a few forests
    • The first domain controller creates more than just a new domain, it also creates a new tree and the root of a new forest.

    Active Directory Replication

    • Replication is the process of maintaining a consistent database of information when it is distributed among several locations.
    • Replication is used for updating Active Directories among domain controllers.

    Active Directory Replication Cont.

    • Intrasite replication: Replication between domain controllers in the same site
    • Intersite replication: Occurs between two or more sites
    • Multimaster replication: Used by AD for replacing AD objects
    • Knowledge Consistency Checker (KCC): Runs on all DCs to determine the replication topology

    The Importance of the Global Catalog Server

    • The first domain controller installed in a forest is automatically designated as a Global Catalog server.
    • Global Catalog servers perform the following vital functions:
      • Facilitates domain and forest-wide searches.
      • Facilitates logon across domains (Users can log on to computers in any domain by using their user principal name (UPN)).

    Designing the Domain Structure

    • Most small and medium businesses choose a single domain for the following reasons:
      • Simplicity
      • Lower costs
      • Easier management
      • Easier access to resources
    • A single-domain structure is usually easier and less expensive than a multidomain structure.

    Summary

    • A Directory service is a database that stores network resource information used to manage users, computers, and resources throughout the network.
    • Use server Manager to install Active Directory Domain Services (AD DS).
    • Installing the first DC in a network creates a new forest and the domain is called the forest root domain.
    • Active Directory data is organized as objects.
    • There are two types of objects in Active Directory: container objects and leaf objects.
    • Leaf objects generally represent security accounts, network resources, and GPOs
    • Active Directory objects can be easily located with search functions in Active Directory Users and Computers and Windows Explorer.
    • Large organizations might require multiple domains, trees, and forests.
    • Directory partitions are sections of the Active Directory database that hold varied types of data and are managed by different processes
    • The forest is the broadest logical Active Directory component.
    • A domain is a primary identifying and administrative unit of Active Directory.

    Active Directory Physical Structure

    • An Active Directory site is a physical location where domain controllers communicate and replicate information.
    • Domain controllers store a copy of the domain data and replicate changes to all other domain controllers.
    • Domain controllers provide data search and retrieval functions for users attempting to locate objects within the directory.
    • Domain controllers provide authentication and authorization services for users who log on to the domain and attempt to access network resources.

    Active Directory’s Logical Structure

    • Four main logical components in Active Directory:
      • Organizational Units (OUs)
      • Domains
      • Trees
      • Forests

    Organizational Units (OUs)

    • An OU is a container used to organize users, resources, and computers into logical administrative units
    • OUs contain these Active Directory objects:
      • User accounts
      • Groups
      • Computer accounts
      • Printers
      • Shared folders
      • Applications
      • Servers
      • Domain controllers

    Domains

    • A domain represents administrative, security, and policy boundaries.
    • Small to medium companies usually have one domain.
    • Larger companies might have multiple domains.

    Trees

    • A tree is a grouping of domains that share a common naming structure.
    • A tree can consist of a parent domain and one or more child domains.

    Forests

    • A forest is a collection of one or more Active Directory trees that provide a common Active Directory environment.
    • All domains within a forest can communicate and share information.
    • A forest can contain a single tree with a single domain, or several trees, each with a hierarchy of parent and child domains.

    Installing Active Directory

    • The Windows Active Directory service is typically referred to as Active Directory Domain Services (AD DS).
    • To install AD DS, use Server Manager.
    • If DNS is not present on the network, the DNS Server Role needs to be installed.

    Installing Active Directory - Deployment Configuration

    • Select one of these options in the Deployment Configuration window:
      • Add a domain controller to an existing domain
      • Add a new domain to an existing forest
      • Add a new forest (choose this option if it is the first DC in the network)
    • You will be prompted for the fully qualified domain name (FQDN) for the new forest root.

    Designing the Domain Structure

    • Most small and medium businesses choose a single domain for these reasons:

      • Simplicity
      • Lower costs
      • Easier management
      • Easier access to resources

    • A single-domain structure is generally simpler and less expensive than a multidomain structure.

    Other Leaf Objects

    • Other leaf objects commonly created in Active Directory:
      • Contact - represents a person associated with the company but not a network user
      • Printer - represents a shared printer in the domain
      • Shared folder - represents a shared folder on a computer in the network

    User Accounts

    • A user account object contains information such as group memberships, account restrictions, profile path, and dial-in permissions.
    • Authentication confirms a user’s identity and assigns permissions and rights.
    • A local user account is authorized to access resources only on that computer.
    • domain user account provides a single logon for users to access resources throughout the domain.
    • Windows creates two built-in user accounts:
      • Administrator
      • Guest

    Groups

    • A group object represents a collection of users with common permissions or rights.
    • Permissions define which resources users can access and what level of access they have.
    • Rights specify what types of actions a user can perform on a computer or network.
    • Groups are used to assign members permissions and rights which is more efficient than assigning permissions and rights to each user separately.

    Computer Accounts

    • A computer account object represents a computer that's a domain controller or domain member.
    • Computer accounts are used to identify, authenticate, and manage computers in the domain.

    Working with Forests, Trees, and Domains

    • Smaller organizations most likely focus on OUs and their child objects.
    • Larger organizations might require an Active Directory structure with several domains, multiple trees, and even multiple forests.
    • The first domain controller creates a new domain, tree, and the root of a new forest.

    Active Directory Replication

    • Replication is the process of maintaining a consistent database of information when the database is distributed across multiple locations.
    • Intrasite replication occurs between domain controllers in the same site.
    • Intersite replication occurs between two or more sites.
    • Multimaster replication is used by Active Directory for replacing Active Directory objects.
    • Knowledge Consistency Checker (KCC) runs on all DCs to determine the replication topology

    The Importance of the Global Catalog Server

    • The first domain controller installed in a forest is automatically designated as a Global Catalog server.
    • Global Catalog servers performs the following vital functions:
      • Facilitates domain and forest-wide searches
      • Facilitates logon across domains (Users can log on to computers in any domain by using their user principal name (UPN).
