When a remote session is abruptly disconnected, the abnormal termination feature lets you lock the managed device or log out the user on the managed device, depending on the configuration in the security settings of the Remote Management policy. The remote session terminates abnormally under the following circumstances:
The networks fails and the Remote Management viewer and the Remote Management service are unable to communicate
The Remote Management viewer is closed abruptly through the task manager.
The network is disabled either on the managed device or on the management console.
Under some circumstances, the Remote Management service might take up to one minute to determine the abnormal termination of the session.
