This document provides information about the supported operating
systems, hardware configurations, software requirements, installation
combinations, and security configurations for Microsoft System Center
Operations Manager 2007. This document focuses on the supported
configurations and only mentions unsupported configurations when
necessary. If operating systems, hardware configurations, software
