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.

Moving FSMO roles

In the Active Directory infrastructure, on certain occasions, FSMO roles will need to be moved from one domain controller to another. Here, I have listed a few scenarios where it will need to consider FSMO roles transfers:

  • Active Directory upgrades: When the infrastructure needs to be upgraded from one Active Directory version to another, the way to do that is to introduce the new domain controllers to the existing infrastructure and then move the FSMO roles. After that, the domain controllers that run older versions can decommission and then increase the forest and domain functional levels to the latest. This will make the migration smooth with minimum identity infrastructure operations impact.
  • Active Directory logical and physical topology: When installing the first domain controller in the infrastructure, it will automatically hold all five FSMO roles. But...
