A configuration and change management system may have installation and configuration processes that include a discovery mechanism for discovering incomplete installations or configuration changes, a cleanup mechanism for placing the system in a state to continue, an installation or configuration mechanism, and a rollback mechanism for rolling back to a defined restore point if a problem is detected. The configuration and change management system may be used for initial installation, as well as configuration changes after installation. The system may be used in a multiple server environment with interdependencies between devices, as well as a multiple services environment with interdependencies between applications and services, including services provided over the Internet.
