This little book covers the daily needs for at administrator Regarding filesystem objects or collections. But I'm missing informations about classes (CLASS is only Mentioned once at page 71 without taking care about public or private declarations, constructors or Destructors, properties with get and let, How to Work Efficiently with functions / methods and creating class instances using new ). So I'm missing some features Regarding Active Directory but I guess thoses features are only included within the "complete" book. Too bad but this book is just too "basic". Very good for newbies but I do not recommend it for IT professionals.
