Majority of Perl books deals with UNIX. However in a real world, whether you like it or not, most IS departments have to deal with Windows NT/2000 servers. These departments also require knowledgeable administrators to take care of this environment. Here is where this book comes in handy. The author, also known from his previous book (WIN32 PERL Programming. The standard extensions) shows us how we can use Perl to do day to day tasks on Windows Servers. The book offers many ready to use scripts and also explains the rationale for using techniques, the way it was used in this book. I rated this book 5 stars because not only it enriched my knowledge but also it saved me many hours of trying to write similar scripts on my own. In essence: A must have!
