you can load and import the Module ActiveDirectory from any server, that has the RSAT tools installed. The users needs to be a member of the localgroup „Remote Management Users“ (Remoteverwaltungsbenutzer) on the target server or you can delegate it to your own group:

#on Targetserver:
Set-PSSessionConfiguration -Name Microsoft.PowerShell -ShowSecurityDescriptorUI

starting 12beAdmin

$Session = New-PSSession -ComputerName TargetServer
Set-ExecutionPolicy -Scope Process -ExecutionPolicy RemoteSigned -Force
Import-Module -PSSession $Session -Name ActiveDirectory
& $yourpath\12beAdmin\12beAdmin.ps1
