Study Notes

Directory Service Role

A directory service is a centralized repository of information about users, computers, and other resources in a network.
Careful planning is crucial for directory services setup to ensure scalability, security, and efficiency.
Directory services provide a centralized management tool, but due to complexity, requires careful planning prior to setup.
Directory services store information about a computer network, and offer features for retrieving and managing that information.

Windows Active Directory (AD)

Lightweight Directory Access Protocol (LDAP) is a protocol used by directory services to access and manage their data. It uses TCP/IP.
Three key features of Active Directory:
- Centralized directory: Stores information about all the network resources.
- Scalability: Can support large numbers of users, computers, and resources.
- Security: Provides granular control over access permissions.
Active Directory's hierarchical structure is based on a logical organizational model, not physical locations.
Policy-based administration in Active Directory allows administrators to manage user permissions, settings, and configurations uniformly across the entire network by creating policy rules.
Windows Active Directory was first used in Windows 2000 Server.

Active Directory Physical and Logical Structures

The physical structure of Active Directory is composed of:
- Servers
- Networks
- Sites
- hardware
A Domain Controller (DC) is a server that stores and replications the information about users, computers, and resources in the directory service. It also manages the network.
Each domain controller contains a full replica of the objects that make up the domain and is responsible for: Storing a copy of the domain data, replicating changes to that data, providing data search and retrieval functions, and providing authentication and authorization services.
An Organizational Unit (OU) is a container object in Active Directory used to organize users, computers, and resources into logical groups.
A tree is a collection of domains that share a common naming context. A forest is a collection of trees.
An Active Directory site is a physical location in which domain controllers communicate and replicate information periodically.

Installing Active Directory

Active Directory Domain Services (ADDS) is installed using the Server Manager tool.
To install ADDS, use Server Manager. If DNS is not already present on the network, install the DNS Server Role.
A Fully Qualified Domain Name (FQDN) is the complete internet domain name with the host name, used to uniquely identify a server or computer within a domain.
Adding a domain controller to an existing domain joins a new server to the established domain structure, while creating a new forest establishes a completely independent domain structure.. Promoting a server to a Domain Controller (DC).
Click the notifications flag in Server Manager and click "Promote this server to a DC".

Inside Active Directory

The Active Directory schema defines the structure and types of objects which can exist within the directory.
Three examples of container objects: Organizational Unit (OU), Domain, and Tree.
Leaf objects contain data, while container objects hold other objects.
The Active Directory Administrative Center (ADAC) streamlines management tasks by providing a graphical interface for organizing users, groups, and resources.

Replication and Directory Partitions

Intrasite replication is the copying of data between servers within the same site. Intersite replication is copying data between different sites.
Five directory partition types:
- Domain Partition: Contains all objects in a domain (users, groups, computers, OUs)
- Schema Partition: Stores the structure and definitions of the directory objects.
- Configuration Partition: Stores configurations that are not relevant to the user base.
- Global Catalog Partition: Holds a partial replica of all the objects in the forest.. Crucial for cross-domain searches.
- Application Directory Partition: Stores information that benefits from application and services.. Allows apps to store data tailored to their needs.
The Knowledge Consistency Checker (KCC) ensures consistency between different copies of the directory data across different sites/servers.

FSMO Roles and Trust Relationships

Five FSMO roles:
- Infrastructure Master; Domain Naming Master; Schema Master; RID Master,PDC Emulator Master
A trust relationship between domains allows users and computers in one domain to access resources in another domain.
Users cannot access resources across domains without a trust relationship because there is no established way to authorize or authenticate outside of the domain boundary.

Global Catalog and Group Policies

The Global Catalog (GC) provides a centralized repository of user and computer information across the entire forest.. Enables fast cross-domain searches.
Two default GPOs created when AD is installed:
- Default Domain Policy
- Default Domain Controllers Policy
Group policies are applied in a defined order, creating a hierarchical structure with priority, with the last one set taking precedence.

PowerShell Commands

Get-ADForest is used to view FSMO roles across the entire forest.
Get-ADDomain is used to retrieve information about a specific domain.
