2.1 Transport

Message transport in the Windows System Resource Manager (WSRM) Protocol uses the DCOM Protocol [MS-DCOM], which uses Remote Procedure Call (RPC) ([C706] and [MS-RPCE]) as its transport.

The WSRM server requires clients to request an RPC authentication level of RPC_C_AUTHN_LEVEL_PKT_PRIVACY (see [MS-RPCE] section 2.2.1.1.8) for method calls to protect the privacy of client-server communication.
