Start or Stop an Application Pool (IIS 7)
Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista
Stopping an application pool causes the Windows Process Activation Service (WAS) to shut down all running worker processes serving that application pool. WAS does not restart these worker processes. An administrator must restart all stopped application pools. All applications routed to a stopped application pool receive 503 Service Unavailable errors.
