1.4 Relationship to Other Protocols
Figure 1: The relationships among the LSAT, LSAD, RPC, and SMB protocols
The Local Security Authority (Translation Methods) Remote Protocol is composed of a subset of opnums in an interface that also includes the Local Security Authority (Domain Policy) Remote Protocol, as specified in [MS-LSAD].
Some messages in this protocol depend on the Netlogon Remote Protocol, as specified in [MS-NRPC], having successfully negotiated security parameters to be used. For more information on the messages that have this requirement, see section 3.1.4.
The Directory Replication Service (DRS) Remote Protocol, as specified in [MS-DRSR], exposes functionality similar to what this protocol achieves, but serves a different purpose. The DRS Remote Protocol can translate names in different syntaxes, but lacks the functionality to translate names from different forests. An application uses one or both protocols, depending on the syntax of names for which the application requires translation.
