1.7 Versioning and Capability Negotiation

This specification covers versioning issues in the following areas:

Supported Transports: The WSRM Protocol supports the transports supported by the DCOM Protocol [MS-DCOM].

Protocol Versions: The following table shows the DCOM interfaces that are defined in the WSRM Protocol and their versions.

Security and Authentication Methods: The WSRM Protocol relies upon the underlying RPC Protocol to obtain the identity of users making method calls ([MS-RPCE] section 3.3.3.4.3). The WSRM server uses this identity to perform access checks, as described in Security Considerations for Implementers (section 5.1).
