The companion CD includes a variety of tools and scripts to help you work more efficiently with Group Policy on computers running Windows 2000, Windows XP Professional, and Windows Server 2003. Several of these tools are discussed in the book; many others are not. You can find documentation for each tool in the GroupPolicyGuideTools folder. Some of these tools are from the Microsoft Windows Server 2003 Resource Kit, so they are designed to be implemented with Windows Server 2003 operating systems.
