1.6 Applicability Statement

  • Article

The DRS Protocol Extensions for SMTP are used by DCs, in a forest, when they are replicating Active Directory contents by using the Directory Replication Service (DRS) Remote Protocol, as specified in [MS-DRSR].

The DRS Protocol Extensions for SMTP are appropriate for linking isolated, regional domains to their forest. The DRS Protocol Extensions for SMTP are appropriate for participation in global forest replicas, such as the configuration NC, schema NC, and the global catalog.

The DRS Protocol Extensions for SMTP cannot be used for replication between DCs that are part of the same site. The extensions cannot be used to replicate a domain between two DCs that are full masters of that domain. They can be used only to replicate a domain between a full master for the domain and a global catalog for that domain or between two global catalogs for that domain.

The DRS Protocol Extensions for SMTP specified in this document are not a general transport mechanism. They are defined only for transport of the IDL_DRSGetNcChanges RPC request and response messages that are part of the DRS Remote Protocol, as specified in [MS-DRSR].
