If, like me, you're considering upgrading from a small peer-to-peer Windows 95/98 network to a proper NT server network and are wondering what NT is all about, this is a great introduction. Better than most introductory books, it clearly explains the advantages and limitations of moving up to NT and the basics of how file server and client/server operations work. However, if you're looking for up-to-the-minute NT information, you'd be better to look elsewhere. Despite the "totally revised and updated" claims, this book is clearly near the end of it's currency. The references to 9600 speed modems and PC's with 16 MB RAM let you know the revisions were not all that complete. But if you're mystified by what NT can do and want an introduction, this book will prepare you for more current/technical books.
