Windows Management Instrumentation (WMI) is a powerful tool built into Windows which enables organizations to manage servers and user PCs connected to their networks. WMI brings the power of managing a Windows network to unprecedented levels. For example, through WMI an administrator can easily write a script that will identify what service packs have been installed on all the machines in the network. WMI is extremely complicated, however, and difficult to understand. This book is written to provide a thorough understanding of how WMI works, as well as being a handy reference to how to use WMI to its fullest potential. System administrators will learn to develop scripts through WMI to access and manipulate their network. Developers will learn how they can use and access the WMI through both the COM interface and the .NET framework.
