5.136 Nt4ReplicationState

  • 發行項

Nt4ReplicationState is an abstract type for the replication state for Windows NT 4.0 operating system BDCs. It is a tuple that contains the following fields:

  • SamNT4ReplicationUSN: A USN that records the replication update sequence number for SAM database updates that are relevant to the Windows NT 4.0 replication protocol. Relevant updates are described in [MS-ADTS] section 3.1.1.7.2.2.

  • SamCreationTime: A FILETIME at which the Windows NT 4.0 replication update sequence number for the SAM database was set to 1.

  • BuiltinNT4ReplicationUSN: A USN that records the replication update sequence number for built-in database updates that are relevant to the Windows NT 4.0 replication protocol. The built-in database contains the objects for built-in principals.

  • BuiltinCreationTime: A FILETIME at which the replication update sequence number for the built-in database was set to 1.

The global variable dc for a DC has an associated field dc.nt4ReplicationState. When a DC owns the PDC FSMO role, this field contains its Nt4ReplicationState. [MS-ADTS] section 3.1.1.7.1.1 describes how the components of dc.nt4ReplicationState are maintained and used to support replication via the Windows NT 4.0 replication mechanism. As an implementation-specific behavior, other DCs might maintain the dc.nt4ReplicationState field as well.
