THIS book has exceeded my expectations. It has already solved/answered many problems/questions I’ve had about GP and AD. It is a one stop problem solver. Given all the 5 stars I saw in the reviews before I bought the book, I thought maybe the publisher had padded the reviews. Not so. This is a must have. It covers the basics and more advanced topics of GP, which is something I needed. An example problem I had: We use Roaming Profiles. We have three remote offices and sometimes printers wouldn’t install when a user went from a remote office to our home office. We also needed a way to automatically reset the default printer when a user roamed to a machine in another office. Page 132-133 of this book tells how to do that with a 5-line script. [This book] deserves more than 5 Stars!
