14.2.1 Remote Assistance Initiation Protocol

The Remote Assistance Initiation Protocol (as specified in [MS-RAI]) is a set of Distributed Component Object Model (DCOM) interfaces for initiating a Remote Assistance (RA) connection to a computer. The Remote Assistance Initiation Protocol allows an authorized Expert to start RA on a remote Novice computer to retrieve data that is required to make an RA connection from the Expert's computer to the Novice's computer.

For purposes of this protocol, an Expert is defined as the side of a RA connection that is able to view the remote screen of the other computer in order to provide help. A Novice is defined as the side of a RA connection that shares its screen with the other computer in order to receive help. The Expert is the DCOM client and the Novice is the DCOM server.

The following are two prerequisites for using this protocol.

  1. The Expert must have the IP address or fully qualified domain name (FQDN) of the Novice's computer in order to use this protocol.

  2. Before the Expert's DCOM call is executed on the Novice computer, DCOM performs a check to verify that the Expert is on the list of authorized RA helpers on the Novice computer.
