The EFSR Protocol uses the interfaces, described in [MS-WCCE], for certificate enrollment, which in turn uses DCOM, as described in [MS-DCOM], as the transport. For all other operations, EFSR directly uses the remote procedure call (RPC) extensions, as described in [MS-RPCE].

The DMRP, VDS, and RSMP Protocols use DCOM as the transport.

The SCMP Protocol uses the interfaces, described in [MS-OAUT], which in turn uses DCOM as the transport.
