Active Directory Administration Cookbook - Second Edition

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.

Removing a trust

When a trust is no longer needed, it can be deleted.

Getting ready

Preferably, you should sign in to the domain controller that is running the Domain Naming Master FSMO role or connect the Active Directory Domains and Trusts console to this specific domain controller.

To find this domain controller, right-click the Active Directory Domains and Trusts node and select Operations Master... from the menu. Alternatively, run the following command from any domain-joined device, member server, or domain controller:

netdom.exe query fsmo

Otherwise, you can use the following line of Windows PowerShell on a domain-joined system that has the Active Directory module for Windows PowerShell installed:

Get-ADForest | Format-List DomainNamingMaster

To remove a shortcut trust, use an account that is a member of the Domain Admins group in the Active Directory domain. To remove other trusts, use an account that is a member of the Enterprise Admins group.
