In terms of desktop management, Group Policy is the cornerstone of a Windows administrator’s arsenal. With Group Policy, you can deploy software, printers and drive mappings. You can configure default settings and manage client behavior. But how do you manage Group Policy? The built-in mechanics for managing Group Policy are simply inadequate for most organizations. Windows administrators either have complete access or no access by their addition and removal from the Group Policy Creator Owners Security Group. Further, Group Policy Object (GPO) management lacks in terms of change control, automated backups, and role based delegation. Microsoft’s Advanced Group Policy Management (AGPM) addresses all of these issues.
