Active Directory Schema versions

The Active Directory Schema is a living platform that receives changes with every new Windows version. You check what each schema version does by looking at the ldf files in “Support\ADPrep” folder on the installation media.

This is done during the Adprep, before you promote a new Windows Server to a Domain Controller.
