Network administrators at organizations using the latest Microsoft servers (Windows 2000 or Windows 2003 servers) and operating systems (Windows 2000 or XP) often use Group Policy Objects (GPOs) to manage their organization's desktops. However, as currently designed, GPOs cannot alter a computer's power management settings. ENERGY STAR's free EZ GPO tool allows a network administrator to centrally control power management settings using GPOs. In addition to setting monitor power management, EZ GPO can also activate "system standby," which places the computer (CPU, hard drive, etc.) to sleep.*

The Microsoft Task Scheduler is an amazing little FREE tool that (in most cases) comes already with your Windows installation and "hides" in the "Control Panel" folder which is located in the "My Computer" folder on your desktop.
