You can run this command only from the computer on which the ISM server is running.
On UNIX, you must log in as user root to use this command. Include this command in the UNIX shut-down script to exit the ISM server automatically whenever the operating system shuts down.
On Windows, the Service Control Manager automatically starts the ISM server when the computer reboots and stops it when the computer shuts down. You must be the Administrator to run this command.
