How to Add Active Directory Schema Snap-In

The Active Directory Schema Snap-In is not an option in MMC by default. If it’s missing from the Add/Remove Snap-In screen, perform these steps.

1. Select the “Start” button, then type “CMD“.
2. Right-click “Command Prompt” and select “Run as Administrator“.
3. Type the following, then press “Enter“:
   regsvr32 schmmgmt.dll
4. You should receive a message that registration succeeded.

Now you should be able to add the snap-in using these steps:

1. Hold the Windows Key and press “R” to bring up the Run box.
2. Type “mmc“, then press “Enter“. The Microsoft Management Console opens.
3. Select “File” > “Add/Remove Snap-In“.
4. Select “Active Directory Schema“, then select “Add“.
5. Select “OK“.

The Active Directory Schema option will now be available to use.
