	// The CreateRemoteObject method creates a disk management server, on the remote machine
	// specified by RemoteComputerName, by invoking DCOM with the class GUID of Disk Management
	// server and the name of the remote machine, which starts the disk management server
	// on the remote machine. The method negotiates for the interface as described in section
	// 3.1.3, and as illustrated in section 4. The client holds a reference to the IDMRemoteServer
	// interface binding on the server, until the client has received an IVolumeClient,
	// or IVolumeClient3 interface binding to the remote server. The client MAY then release
	// the IDMRemoteServer interface on the server.
	//
	// Return Values: The method MUST return 0 or a nonerror HRESULT on success, or an implementation-specific
	// nonzero error code on failure (as specified in [MS-ERREF]; see also section 2.2.1
	// for HRESULT values predefined by the Disk Management Remote Protocol).
