Group Policy, Profiles, and Intellimirror for Windows 2003, Windows 2000, and Windows XP by Jeremy Moskowitz
The Group Policy infrastructure in the Windows Server products enable IT administrators to automate one-to-many management of users and computers - simplifying administrative tasks and reducing IT costs. With the debut of Group Policy Management Console (GPMC) with Server 2003, policy-based management is even easier. Administrators can efficiently implement security settings, enforce IT policies, and distribute software consistently across a given site, domain, or range of organizational units.
