To install the active directory module using PowerShell, you need Remote Server Administrator Tools (RSAT) on the server. It should be available in the Roles and Features section of the windows server operating system as shown below and you can enable it from the GUI as well.
If you can’t find the RSAT then you can download it from the below location, appropriate to your OS version.
Once you have the RSAT tool available in your system, you can use the PowerShell command to enable this feature. To get the Active Directory tools features available in the system, use the below command.
We need RSAT-AD-Tools on the windows system and we will include all sub-features. You can also other AD tools as per your requirement.
