Performing System Management Tasks

Scheduling Shutdowns 

Though system shutdowns are a rare occurence, there are situations that
do require you shut down your computer.  For example, you will need to
shut it down if you are changing the configuration, changing system
security, or moving the system to another location.

Since all users lose access to the computer when you perform a shutdown,
shutdowns greatly impact productivity and business deadlines.  As system
manager, you should schedule any planned shutdowns at a time least likely
to interfere with users' productivity.
