The client creates an RPC binding handle to the server RPC method endpoint when an RPC method is called. For more information on binding handles, see [C706]. The client MAY create a separate binding handle for each method invocation, or it MAY reuse a binding handle for multiple invocations. The client MUST create an authenticated RPC binding handle.
If the RPC interface is available, the client MUST use the RPC interface to configure the RRAS server remotely. The client SHOULD use the registry store configuration using [MS-RRP] to configure RRAS server as defined in section 2.2.3 when the RPC interface is not available.
