Just published a few weeks ago, the Windows Vista Resource Kit is a must have book if you're responsible for deploying Windows Vista!! I always try and keep my resource kit library up-to-date as they put so much information at your finger tips.
Another recent addition to my library is the Windows Server 2008 Resource Kit, if you're an IT Pro these books are invaluable.
Your definitive resource for deployment and operations—straight from the experts.
Get the definitive reference for deploying, configuring, and supporting Windows Vista—with expert insights from Microsoft Most Valuable Professionals (MVPs) and the Windows Vista Team at Microsoft. With additions and updates for SP1, this official Microsoft RESOURCE KIT provides more than 1,700 pages of in-depth technical guidance on automating deployment; implementing security enhancements, including Windows® Firewall and Windows Defender; administering Group Policy, files, folders, programs, and devices; using Windows Internet Explorer® 7; configuring network connections; and troubleshooting. You also get more than 170 timesaving scripts to help automate administrative tasks, additional job aids, and an eBook of the entire RESOURCE KIT with bonus chapters on a companion DVD.
