What is GPMC tool?

The Group Policy Management Console (GPMC) is a tool for managing group policies in Windows Server 2003. It provides administrators a single consolidated environment for working on group policy-related tasks. GPMC provides a single interface with drag-and-drop functionality to allow an administrator to manage group policy settings across multiple sites, domains, or even forests. GPMC is used to back up, restore, import, and copy group policy objects. It also provides a reporting interface on how group policy objects (GPOs) have been deployed.
