This is a very well written book with every page being very useful and consise. Each page is a treasure, which is a far cry to a lot of tech books filled with fluff and opinion these days.
I am both a Solaris and Windows system administrator, and though I dearly love GUI interface to access complex things, I would not like to repeat these tasks on hundreds of desktops. With this book, I found that I could automate chores and remotely configure desktops. There are so many gems in this book, this is a MUST have for any PowerUser, Admin, or anyone simply wanting to use command-line alternatives.
In the beginning Stanek covers the differences between Windows and MS-DOS command shells (cmd vs command) and environments, Win2k3 Reskit, and Cmd Shell fundamentals (similar but slightly different that ol' DOS Batch files). He then jumps into (Chap 4) one of the most important topics, task scheduling from the command line, which is essential for automation, especially for backups, virus updates, etc. The following chapters, he covers topics like registry maintence, process management, event logging, disk maintences (RAID, partitioning, formatting, etc.). The process management part can be useful in killing spyware processes, especially for spyware that blocks out such functionality through the GUI.
My favorite sections that have the most impact for me is Active Directory tools (account creation, groups, etc.), printer management, and network management. I tried to figure out, for instance, the enigma of "netsh" command before without success, and this book helped me on that powerful tool. Now armed with this knowledge, I can remotely configure desktops IP addresses, and monitor the health of printers, without even getting out of my seat.
All in all, this book is excellent. Very well organized chapters and flow of information, and very well written. It's works both for general reading and also as a reference.
