When you connect to Parallels RAS and launch a published resource, a session is created on the server side. You can manage sessions from the Sessions menu as follows:
Disconnect session. Disconnect from the remote server. The session, and all opened remote applications, will continue to run on the server. To reconnect to the section, open any published resource.
Disconnect all RAS sessions. Disconnect all active sessions (not just the current one). The sessions will continue to run on the remote server.
Send Ctrl+Alt+Delete. Send Ctrl+Alt+Delete to the remote session.
Session Information. Display the session information. For this menu to be enabled, you need to select a running published resource.
