Articulate and technically astute, the author comes across as a trusted advisor, providing an expert's view of designing the layout of your company's Active Directory schema. In realistic terms, he shows you how AD can coexist with Unix directories. The book not only provides a collection of screen shots (though there are hands-on tutorials for specific tasks) but also a nicely in-depth tour of what Internet directories are and what advantages Active Directory offers. Case studies on sample domains and organization units (OUs) for sample companies, including a model global corporation, will help you cope with the design of even the most complex directories. Hints for limiting "domains" and favoring the more flexible "organizational units" (OUs) will also help you think in Windows 2000 terms.

Later sections of the book delve into Active Directory Services Interface (ASDI) scripting using Windows Script Host (WSH), Visual Basic, and even ASPs for browser-based administration. The tips and sample scripts for a variety of common administrative tasks, such as adding new users, changing passwords, and the like, assume very little programming background. This focus on the practical side of administration rounds out an extremely useful and technically savvy guide to Windows 2000 that can definitely simplify the life of any administrator, manager, or developer upgrading to the latest Windows. --Richard Dragan
