Mastering Active Directory

By: Dishan Francis

Overview of this book

Active Directory is a centralized and standardized system that automates networked management of user data, security, and distributed resources and enables interoperation with other directories. If you are aware of Active Directory basics and want to gain expertise in it, this book is perfect for you. We will quickly go through the architecture and fundamentals of Active Directory and then dive deep into the core components, such as forests, domains, sites, trust relationships, OU, objects, attributes, DNS, and replication. We will then move on to AD schemas, global catalogs, LDAP, RODC, RMS, certificate authorities, group policies, and security best practices, which will help you gain a better understanding of objects and components and how they can be used effectively. We will also cover AD Domain Services and Federation Services for Windows Server 2016 and all their new features. Last but not least, you will learn how to manage your identity infrastructure for a hybrid-cloud setup. All this will help you design, plan, deploy, manage operations on, and troubleshoot your enterprise identity infrastructure in a secure, effective manner. Furthermore, I will guide you through automating administrative tasks using PowerShell cmdlets. Toward the end of the book, we will cover best practices and troubleshooting techniques that can be used to improve security and performance in an identity infrastructure.

How does replication work?

By now, we know the logical and physical components involved with the Active Directory replication process. It is time to put all these together and understand how exactly the Active Directory replication happens.

In the Active Directory environment, there are mainly two types of replication:

  • Intra-site replications
  • Inter-site replications

Intra-site replications

As the name implies, this covers the replications happening within a site. By default, (according to Microsoft) any domain controller will be aware of any directory update within 15 seconds. Within the site despite the number of domain controllers, any directory update will be replicated in less than a minute:

Within the site, the replication...
