Once the Schema update is complete, it is replicated from the schema master to all other DCs in the directory.

To update the schema of a forest, you must have access to the schema master.

There can be only one schema master in the whole forest.

This is similar to the role given to a primary domain controller (PDC) in earlier versions of Windows (such as Microsoft Windows NT 4.0), in which the PDC is responsible for processing all updates in a given domain.A multi-master enabled database, such as the Active Directory, provides the flexibility of allowing changes to occur at any DC in the enterprise, but it also introduces the possibility of conflicts that can potentially lead to problems once the data is replicated to the rest of the enterprise.One way Windows 2000/2003 deals with conflicting updates is by having a conflict resolution algorithm handle discrepancies in values by resolving to the DC to which changes were written last (that is, “the last writer wins”), while discarding the changes in all other DCs.This DC is the only one that can add or remove a domain from the directory.

For certain types of changes, Windows 2000/2003 incorporates methods to prevent conflicting Active Directory updates from occurring.

To prevent conflicting updates in Windows 2000/2003, the Active Directory performs updates to certain objects in a single-master fashion.
