Remote Assistance is a feature that allows a user to temporarily view or control a remote computer over a network or the Internet to resolve issues without directly touching the unit. It is based on the Remote Desktop Protocol.
Helpers offering remote assistance can open multiple simultaneous sessions—one for each remote computer. However, users seeking assistance from helpers can have only one RA session waiting for a connection. Connect invitations can be sent to multiple recipients—any of which may connect. All subsequent connect attempts will be blocked until the first helper disconnects, after which another helper may connect. If the user disconnects the session, the RA application terminates and no further connections are allowed.
