"Finally, a step-by-step VBScripting book to make you look like a programmer without the time and sweat! Don't waste your time searching the Internet for examples--this book does it for you!"
--Greg A. Marino, Senior Systems Engineer/Consultant, Westtown Consulting Group, Inc.
Visual Basic Scripting (VBScript) and Windows Management Instrumentation (WMI) are vital tools for systems administrators grappling with the increasing complexity of Windows technologies. However, busy admins have been without a straightforward guide to scripting...until now.
Managing Windows® with VBScript and WMI explains how Windows administrators can effectively use VBScript to automate common administrative tasks and simplify complex ones. Detailed coverage of security concerns provides admins with the means for safely using VBScript in Windows environments. The book is organized around the problems you face daily, with reusable examples and coverage of Windows NT, Windows 2000, Windows XP, and Windows 2003.
This user-friendly reference demystifies scripting and then shows you how to produce new scripts from scratch. You will be producing useful scripts right away as you study the VBScript language and learn how to control nearly every aspect of the Windows operating system with WMI and the Active Directory Services Interface (ASDI). You will be able to build your own administrative Web pages and use advanced scripting technologies such as script encryption, scripting components, and script security. The book closes with still more ready-made example scripts accompanied by complete line-by-line explanations. The CD includes all the code from the book and trial versions of PrimalScript 3.0 and VbsEdit. A companion Web site provides updates and errata.
Inside you will find answers to such questions as:
How do you write effective logon scripts? Chapter 11
How do you write scripts that query and modify user and group information? Chapter 16
How can you query the IP addresses from multiple network adapters in multiple remote computers? Chapter 19
How can you design, write, run, test, and debug your own administrative Web pages? Chapter 24
How can you reuse code between various scripts? Chapter 25
