✅ Step 1: Log in to DC2
Use an account that is a member of the Schema Admins, Enterprise Admins, and Domain Admins groups.
✅ Step 2: Register the Schema Snap-in
The Schema snap-in is not loaded by default.
Open Command Prompt as Administrator.
Type the following command to register the schema management DLL:
powershell
Copy
regsvr32 schmmgmt.dll
✅ Step 3: Open MMC (Microsoft Management Console)
Press Windows + R, type mmc, and hit Enter.
In MMC, go to File > Add/Remove Snap-in.
Select Active Directory Schema, then click Add > OK.
✅ Step 4: Connect to DC2
In the Active Directory Schema console, right-click Active Directory Schema and select Change Active Directory Domain Controller.
In the dialog box, select DC2 and click OK.
✅ Step 5: Transfer the Schema Master Role
Right-click Active Directory Schema again and select Operations Master.
In the Change Schema Master dialog box, confirm that DC2 is shown as the target.
Click the Change button to transfer the Schema Master role to DC2.
Click Yes when prompted to confirm the transfer.
✅ Step 6: Verify the Transfer
In the same dialog box, ensure that DC2 is now listed as the Schema Master.
Optionally, run the following command in PowerShell to verify:
netdom query fsmo
The Schema Master should now be DC2.
