Exceptions Thrown: This method throws an exception with the exception code RPC_S_ACCESS_DENIED (0x00000005) if the client is not an administrator on the RRASM server, with access permission to perform the operation.<347>

The opnum field value for this method is 14.

When processing this call, the RRASM server SHOULD do the following:

  • Validate as specified in section 3.3.4 whether this method was called by a client that is an administrator of the RRASM server.

  • Call the abstract interface Invoke RASRPC method specifying the operation and the parameters to enable RRAS server to perform the required management task.

  • If all validation is successful, return the installed protocol information as provided by the RRAS server.
