Schema Directory Partition

Updated: November 25, 2009

Applies To: Windows Server 2008 R2

The schema is stored in its own partition (the schema directory partition). The schema directory partition is replicated among all the domain controllers in the forest, and any change that is made to the schema is replicated to every domain controller in the forest. Because the schema dictates how information is stored, and because any changes that are made to the schema affect every domain controller, changes to the schema should be made only when necessary — through a tightly controlled process — after testing has been performed to ensure that there will be no adverse effects on the rest of the forest.
