3 Protocol Details

The Message Queuing (MSMQ): Queue Manager Management Protocol is used for performing management operations on the MSMQ installation and a queue.

The client side of this protocol is simply a pass-through. That is, there are no timers or other states required on the client side. Calls made by a higher-layer protocol or an application are passed directly to the transport, and the results returned by the transport are passed directly back to the higher-layer protocol or application.

The client MUST have administrator privileges on the server machine.

This protocol permits establishing a connection to an RPC server. For each connection, the server uses the underlying RPC protocol to retrieve the identity of the invoking client call, as specified in [MS-RPCE] section The server uses this identity to perform method-specific access checks, as specified in section 3.1.4.

The methods comprising this RPC interface all return 0x00000000 on success and a nonzero implementation-specific error code on failure. Unless otherwise specified in the following sections, a server-side implementation of this protocol uses any nonzero Win32 error value to signify an error condition, as specified in section 1.8. The client side of the Message Queuing (MSMQ): Queue Manager Management Protocol does not need to interpret the error codes returned from the server; instead, the client side can return the error code unprocessed to the invoking application without taking any protocol action.

Note The phrases "client side" and "server side" refer to the initiating and receiving ends of the protocol, respectively, rather than to client or server versions of an operating system. The receiving end of the protocol—the server side—behaves the same regardless of whether the server side is running on a client or server.
