On both server and client, Windows ships with the “ActiveDirectory” PowerShell module. It adds numerous cmdlets to manage users and resources in the Active Directory.
By default, the module is hidden though. To enable it on clients, with Administrator privileges run this:
$element = Get-WindowsCapability -Online -Name "Rsat.ActiveDirectory.DS*" Add-WindowsCapability -Name $element.Name -Online
On a server, again use Administrator privileges and run this:
Install-WindowsFeature RSAT-AD-PowerShell Add-WindowsFeature RSAT-AD-PowerShell
