As part of Microsoft's IntelliMirror technologies, Group Policy aims to reduce the cost of supporting users. IntelliMirror technologies relate to the management of disconnected machines or roaming users and include roaming user profiles, folder redirection and offline files. Group Policy Objects don't necessarily need Active Directory; Novell has supported roaming profiles since Windows 2000 with their ZENworks Desktop Management software package, and starting with Windows XP also supports group policy objects.
