Study Notes

Active Directory Physical Structure

An Active Directory site is a physical location where domain controllers communicate and replicate information.
Each domain controller:
- Stores a copy of the domain data and replicates changes to all other domain controllers.
- Provides data search and retrieval functions for users.
- Provides authentication and authorization services for users.

Active Directory Logical Structure

Active Directory is organized into four components:
- Organizational units (OUs)
- Domains
- Trees
- Forests
OU is a container that organizes users and resources into logical administrative units.

Active Directory Objects

OUs contain Active Directory objects such as user accounts, groups, computer accounts, printers, shared folders, applications, servers, and domain controllers.
A domain represents administrative, security, and policy boundaries
Small to medium companies usually have one domain while larger companies may have several domains to separate geographical regions or administrative responsibilities.

Active Directory Administrative Center (ADAC)

Use ADAC to:
- Create and manage users, groups, and computer accounts.
- Manage OUs.
- Connect to other domain controllers.
- Change the domain’s functional level and enable the AD Recycle Bin.

Active Directory Schema

An object is a grouping of information that describes a network resource.
The schema defines the types of objects that can be stored in Active Directory and what type of information is stored in each object.
Schema classes define the types of objects in Active Directory.
Schema attributes define the type of information stored in each object.
The information stored in each attribute is called the attribute value.

Active Directory Container Objects

Container objects contain other objects and are used to organize and manage users and resources on the network.
Container objects act as administrative and security boundaries.
Three container objects are found in AD:
- Organizational Units
- Folder Objects
- Domain objects

Organizational Units (OU)

An OU is a primary container object for organizing and managing resources in a domain.
OUs can be used to organize objects into logical administrative groups that can be configured with specific policies.
Authority of an OU can be delegated.
Nesting OUs builds a hierarchical Active Directory structure that mimics the corporate structure for easier object management.

Folder Objects

Folder objects are created by default and contain different objects.
Five default folder objects are:
- Builtin - houses default groups created by Windows
- Computers - default location for computer accounts
- Foreign Security Principals - contains user accounts from other domains
- Managed Service Accounts - created specifically for services to access domain resources
- Users - Stores two default users (Administrator and Guest) and several default groups

Domain Objects

Domain objects are the core logical structure in AD, and they contain OU and folder container objects as well as leaf objects.
Larger companies may use multiple domains to separate administration, define security boundaries, and define policy boundaries.

Active Directory Leaf Objects

Leaf objects don’t contain other objects; they represent security accounts, network resources, or a Group Policy Object (GPO).
Security account objects include users, groups, and computers.
Network resource objects include servers, domain controllers, file shares, printers, etc.

Other Active Directory Leaf Objects

Other commonly created leaf objects include:
- Contact - 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 then the account is assigned permissions and rights.
Local user accounts are authorized to access resources only on that computer.
Domain user accounts enable a single logon for users to access all resources in the domain.
Windows creates two built-in user accounts: Administrator and Guest.

Active Directory Groups

Group objects represent 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.
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.
