By: Sander Berkouwer

Overview of this book

Updated to the Windows Server 2022, this second edition covers effective recipes for Active Directory administration that will help you leverage AD's capabilities for automating network, security, and access management tasks in the Windows infrastructure. Starting with a detailed focus on forests, domains, trusts, schemas, and partitions, this book will help you manage domain controllers, organizational units, and default containers. You'll then explore Active Directory sites management as well as identify and solve replication problems. As you progress, you'll work through recipes that show you how to manage your AD domains as well as user and group objects and computer accounts, expiring group memberships, and Group Managed Service Accounts (gMSAs) with PowerShell. Once you've covered DNS and certificates, you'll work with Group Policy and then focus on federation and security before advancing to Azure Active Directory and how to integrate on-premise Active Directory with Azure AD. Finally, you'll discover how Microsoft Azure AD Connect synchronization works and how to harden Azure AD. By the end of this AD book, you’ll be able to make the most of Active Directory and Azure AD Connect.

  • Disable a domain controller as a global catalog.

Getting ready

Before enabling or disabling domain controllers as global catalog servers, the placement rules should be considered.

Global catalogs are of importance in environments with multiple domains. Except for Active Directory environments in which the Active Directory Recycle Bin is enabled, the placement of global catalogs should be considered in close relation to the domain controller holding the Infrastructure Master FSMO role.

In environments where we consider the placement of global catalogs, either of the following...
