1.6 Applicability Statement
This protocol is primarily designed to provide a peer-to-peer system for exchanging messages over reliable connections. Its use of bidirectional RPC connections to RPC dynamic endpoints means that it is applicable only when the participants can directly contact each other. This protocol requires that the partners refer to each other by NetBIOS name; that is, the participants need to use a name service. Also, the use of Mutual Authentication in conjunction with the protocol's reliance on NetBIOS means that the participants are required to be either in the same domain or in domains that have a trust relationship.
