3.2.5 Message Processing Events and Sequencing Rules

The novice starts listening on all IP Address and port pairs for an incoming TCP connection from the expert machine and generates a Remote Assistance Connection String (section 2.2 of [MS-RAI]).

After a TCP Connection is established, a Remote Desktop connection (described in section 3.3 of [MS-RDPBCGR]) MUST be initiated using Extensions to the Remote Desktop Protocol described in section 2.2.7.

Upon completion of Remote Desktop Connection, depending on the negotiated Remote Assistance protocol version, a Remote Assistance Session MUST be established as described in sections 3.4, 3.6 and 3.8.
