PowerShell in Practice covers 205 individually tested and ready-to-use techniques, each explained in an easy problem/solution/discussion format. The book has three parts. The first is a quick overview of PowerShell. The second, Working with People, addresses user accounts, mailboxes, and desktop configuration. The third, Working with Servers, covers techniques for DNS, Active Directory, Exchange, IIS, and much more. Along the way, you'll pick up a wealth of ideas from the book's examples: 1-line scripts to full-blown Windows programs.
