1.7 Versioning and Capability Negotiation

  • Article

This document covers versioning issues in the following areas:

  • Supported transports: The DFS: Namespace Management Protocol uses RPC over SMB1.x or SMB2 as its only supported transport. For more information on transport specifications, see section 2.1.

  • Protocol versions: The RPC interface for this protocol has a single version number of 3.0. This protocol can be extended without altering the version number by adding RPC methods to the interface, with opnums positioned numerically beyond those defined in this specification. A client determines whether such methods are supported by attempting to invoke the method; if the method is not supported, the RPC server returns an "opnum out of range" error. RPC versioning and capacity negotiation in this situation is specified in [C706] and [MS-RPCE].<3>

  • Security and authentication methods: As specified in [MS-RPCE].

  • Capability negotiation: None.
