Schema Attribute Definition Replication

Applies To: Windows Server 2008

The schema is the Active Directory component that defines all the objects and attributes that the directory service uses to store data. To ensure data integrity on directory objects, it is imperative that attribute definitions are replicated. Replication between domain controllers requires that the schema be consistent. If the schema is not consistent, replication failures occur for all domain controllers with inconsistent schema versions.
