I have a Windows 2008 Small Business Server I wish to retire. Currently it holds the FSMO roles. When I go to add the Active Directory Schema snap-in to a MMC, so that I can transfer it to a new Windows 2012 server domain controller, it is not available in the list of "Available Snap-ins". Please note that I have run "regsvr32 schmmgmt.dll" from an elevated command prompt prior to starting the MMC.
How do I add the Active Directory Schema to the MMC?
