   • Automate the migration of Group Policy settings, security permissions, or other AD-related configurations using PowerShell.
8. Active Directory Security and Permissions:
   • PowerShell provides capabilities for managing security and permissions in Active Directory.
   • Use cmdlets like Set-ADACL, Add-ADPermission, or Remove-ADGroupMember to modify security permissions, grant or revoke access rights, or manage group memberships.
   • Automate security-related tasks, such as updating permissions on AD objects or managing group memberships, using PowerShell scripts.
9. Active Directory Replication Monitoring:
   • PowerShell allows you to monitor and troubleshoot Active Directory replication.
   • Utilize cmdlets like Get-ADReplicationPartnerMetadata, Get-ADReplicationFailure, or Get-ADReplicationUpToDatenessVectorTable to retrieve replication information, detect replication failures, or analyze replication latency.
   • Automate replication monitoring tasks, schedule replication health checks, or trigger alerts based on replication status using PowerShell.
10. Active Directory Disaster Recovery:
    • PowerShell can be used to automate Active Directory disaster recovery tasks.
    • Develop PowerShell scripts or modules that automate tasks such as backing up and restoring AD databases, performing authoritative or non-authoritative restores, or recovering deleted AD objects.
    • Utilize PowerShell’s error handling, logging, and reporting capabilities to create robust AD disaster recovery automation solutions.
11. Active Directory Module for Windows PowerShell:
    • The Active Directory Module for Windows PowerShell is a PowerShell module that provides cmdlets specifically designed for managing Active Directory.
    • This module needs to be installed and imported into PowerShell before you can use the Active Directory-related cmdlets.
    • The module provides a set of cmdlets for creating, modifying, and querying AD objects, as well as managing domains, trusts, and replication.
12. Group Policy Preferences:
    • Group Policy Preferences (GPP) is an extension to Group Policy that allows more granular control over settings and configurations.
    • PowerShell provides cmdlets to manage Group Policy Preferences, such as Get-GPPrefRegistryValue, Set-GPPrefRegistryValue, or Remove-GPPrefRegistryValue.
    • You can use these cmdlets to create, modify, or remove registry-based preferences, mapped drives, printers, scheduled tasks, and more.
13. Active Directory Web Services (ADWS):
    • Active Directory Web Services (ADWS) is a web service interface for managing Active Directory using PowerShell.
    • ADWS allows remote administration of Active Directory without the need to install the Active Directory Management Tools on the local machine.
    • You can use the New-PSSession cmdlet to establish a remote PowerShell session with an ADWS endpoint and then use AD-related cmdlets within that session.
14. Active Directory Administrative Center (ADAC) Integration:
    • Active Directory Administrative Center (ADAC) is a graphical management tool for Active Directory.
    • PowerShell integrates with ADAC, allowing you to perform administrative tasks through a GUI and generate equivalent PowerShell commands.
