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.

DFS replication issues

After Windows Server 2003, FRS is not used for SYSVOL replication. It is being replaced by DFS. But if you are upgrading AD DS from an older version, it will be still in use and migration from FRS to DFS is required. We have covered this in Chapter 11, Active Directory Services.

The SYSVOL folder in a DC includes the domain's public files such as Group Policy files, batch files, login scripts, and so on. Healthy replication of SYSVOL is required to maintain a functional AD environment. When there are SYSVOL replication issues, you may experience issues such as:

  • Group Policies are applied partially or not applied at all
  • Group Policies are being applied to part of the target object group
  • Login scripts are not running

We also can see the following events in the event viewer under the ;DFS Replication log and System log files:
