1.4 Relationship to Other Protocols
The Messenger Service Remote Protocol suite is dependent on RPC (as specified in [C706]), the Server Message Block (SMB) Protocol (as specified in [MS-SMB]), and the mailslot datagram delivery service (as specified in [MS-MAIL]), which are its transports.
The Messenger Service Remote Protocol uses NetBIOS names (as specified in [RFC1001] section 14 and [RFC1002] section 4.1) to identify message recipients.
