I bought this book with basic knowledge of Terminal Services, but even if I hadn't I would still be very comfortable with it after reading this book. As an MIS manager, my goal was to find a book that would make me knowledgable-enough to explain the technology to my technicians, as well as my customers. This book did the job. After highlighting much of the it, I've turned it over to my staff for in-depth comprehension. I found the book very clear, thorough, and straight-to-the-point - a very quick read. I never give recommendations, but felt it justified here.
