8 Chapters • 40 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Introduction to Active Directory Fundamentals

  • Lesson 1 • AD Schema and Data Store

    Describes the AD schema as the blueprint for all objects and the NTDS.dit database as the data store. Prepares learners for object management in later chapters.

  • Lesson 2 • Authentication Protocols in AD

    Introduces Kerberos and NTLM as the primary authentication mechanisms in AD environments. Provides the security foundation needed for advanced topics.

  • Lesson 3 • Directory Services and AD Overview

    Covers the purpose of directory services and how AD fits into Windows-based networks. Establishes context for all subsequent AD administration topics.

  • Lesson 4 • Core AD Logical Components

    Explains domains, trees, forests, and organisational units as the logical building blocks of AD. Learners map these structures to real enterprise scenarios.

  • Lesson 5 • AD Physical Infrastructure

    Introduces domain controllers, global catalog servers, and replication topology. Connects physical infrastructure to logical AD design decisions.

Chapter 2See details

Installing and Configuring AD Domain Services

  • Lesson 1 • Promoting a Server to Domain Controller

    Covers the dcpromo process and the Active Directory Domain Services Configuration Wizard. Learners promote servers into new and existing domains.

  • Lesson 2 • Post-Installation Verification

    Teaches validation steps using built-in tools to confirm a healthy AD deployment. Connects to troubleshooting skills developed in later chapters.

  • Lesson 3 • Planning an AD DS Deployment

    Covers hardware, OS, and network prerequisites before installation begins. Proper planning prevents common post-deployment issues addressed later in the course.

  • Lesson 4 • Configuring Additional Domain Controllers

    Explains adding redundant DCs for high availability and load distribution. Learners configure replication and verify multi-DC environments.

  • Lesson 5 • Installing the AD DS Role

    Walks through adding the AD DS role via Server Manager and PowerShell. Learners practise both GUI and command-line installation methods.

Chapter 3See details

Managing Users, Groups, and Computers

  • Lesson 1 • Group Types and Scopes

    Explains security vs. distribution groups and the AGDLP/AGUDLP nesting strategy. Learners apply correct group scopes to control resource access efficiently.

  • Lesson 2 • Managing Computer Accounts

    Covers joining machines to the domain, managing computer objects, and resetting accounts. Prepares learners for Group Policy application to computer objects.

  • Lesson 3 • Bulk Operations with PowerShell

    Introduces the Active Directory PowerShell module for bulk user and group management. Learners write scripts to automate repetitive administrative tasks.

  • Lesson 4 • Delegation of Control

    Teaches granting granular administrative permissions over OUs without full domain admin rights. Reinforces the principle of least privilege in AD management.

  • Lesson 5 • Creating and Managing User Accounts

    Covers user account creation, attribute configuration, and lifecycle management. Builds the object management skills required for group and policy administration.

Chapter 4See details

Group Policy Design and Administration

  • Lesson 1 • Creating and Linking GPOs

    Covers creating GPOs in the Group Policy Management Console and linking them to sites, domains, and OUs. Learners practise scoping policies to the correct targets.

  • Lesson 2 • Configuring Security and Desktop Settings

    Teaches configuring password policies, account lockout, software restriction, and desktop settings via GPO. Directly applies to hardening covered in the security chapter.

  • Lesson 3 • Troubleshooting Group Policy

    Covers gpresult, RSOP, and event log analysis to diagnose GPO application failures. Builds diagnostic skills applicable to all AD troubleshooting scenarios.

  • Lesson 4 • Group Policy Architecture

    Explains GPO structure, SYSVOL storage, and the client-side extension processing model. Provides the conceptual foundation for all GPO design decisions.

  • Lesson 5 • GPO Filtering and Targeting

    Explains security filtering, WMI filters, and item-level targeting to apply GPOs selectively. Learners reduce policy conflicts through precise targeting techniques.

Chapter 5See details

AD Sites, Replication, and DNS Integration

  • Lesson 1 • DNS Integration with Active Directory

    Covers AD-integrated DNS zones, dynamic updates, and SRV record registration. Proper DNS configuration is prerequisite to reliable DC location and authentication.

  • Lesson 2 • Troubleshooting Replication Failures

    Teaches diagnosing replication errors using repadmin, dcdiag, and event logs. Learners resolve USN rollback, lingering objects, and connectivity-related failures.

  • Lesson 3 • Designing AD Sites and Subnets

    Covers creating sites, associating subnets, and aligning site design with physical network topology. Correct site design reduces unnecessary replication and authentication traffic.

  • Lesson 4 • Configuring Site Links and Replication

    Explains site link objects, replication schedules, and the KCC's role in generating replication topology. Learners tune replication to balance currency and bandwidth.

  • Lesson 5 • Intrasite vs. Intersite Replication

    Distinguishes automatic intrasite replication from scheduled intersite replication and their protocols. Learners select appropriate replication protocols for each network segment.

Chapter 6See details

Active Directory Security and Hardening

  • Lesson 1 • Securing AD Administrative Accounts

    Covers securing built-in accounts, using Managed Service Accounts, and enforcing just-in-time access. Directly mitigates the privileged account abuse threats identified earlier.

  • Lesson 2 • Privileged Access and Tiered Administration

    Covers the tiered administration model and Privileged Access Workstations to isolate high-value credentials. Reduces blast radius of compromised accounts.

  • Lesson 3 • Auditing and Monitoring AD Events

    Configures advanced audit policies to log authentication, object access, and privilege use events. Provides the visibility needed to detect and respond to AD-based attacks.

  • Lesson 4 • AD Attack Surface and Threat Landscape

    Identifies common AD attack vectors including pass-the-hash, Kerberoasting, and DCSync. Understanding threats drives the hardening decisions covered throughout this chapter.

  • Lesson 2 • AD Backup Strategies

    Covers Windows Server Backup, system state backups, and backup frequency planning for AD. A solid backup strategy is the prerequisite for all recovery procedures.

  • Lesson 3 • FSMO Role Management

    Explains the five FSMO roles, their impact on AD operations, and procedures for transferring or seizing them. Prepares learners for planned maintenance and emergency recovery.

  • Lesson 4 • Restoring Deleted Objects

    Teaches using the AD Recycle Bin and authoritative restore to recover accidentally deleted objects. Learners practise both methods and understand when each applies.

  • Lesson 5 • Routine AD Health Maintenance

    Covers scheduled tasks including tombstone cleanup, database defragmentation, and health checks. Regular maintenance prevents the failures addressed in recovery sections.

Chapter 8See details

Advanced AD Features and Hybrid Identity
