My latest creation, Windows Server Cookbook, has been submitted to the O'Reilly production crew.  If you liked Active Directory Cookbook, you are going to really like Windows Server Cookbook, which covers a little bit of everything.  See the TOC for the complete list of recipes.

The book is due to be released in March.  I'm working on getting all the code samples on this web site before then.  There are over 300 recipes, so there will be a bunch of code (and yes, I'm going to provide parallel Perl examples).  Stay tuned for more!
