In many environments, you might need to perform unscheduled maintenance on a computer. For example, an organization might have an Apache Web server that must be shut down immediately. In this case, you can temporarily block all jobs, events, and data for a particular computer, including jobs that remotely monitor a computer, by placing the computer in machine maintenance mode. For more information about placing computers in maintenance mode, see the Administrator Guide for AppManager, available on the AppManager Documentation page.
