WMI (Windows Management Instrumentation) is a black hole to many Windows administrators, yet it is a hidden jewel that can be exploited with a little effort to automate and improve common system management tasks. Getting information about WMI scripting, the applications that supportWMI, and how to approach bringing it all together to make things happen are some of the reasons why administrators don't use WMI. Alain Lissoir's books cover WMI in depth for Windows 2000 and Windows .NETServer 2003 in a highly approachable manner. - Tony Redmond, VP and CIO, HP Consulting and Integration
