The startup of this service signals other services that the Security Accounts Manager (SAM) is ready to accept requests. Disabling this service will prevent other services in the system from being notified when the SAM is ready, which may in turn cause those services to fail to start correctly. This service should not be disabled. Fix: (1) GPO: Computer Configuration\Windows Settings\Security Settings\System Services!Security Accounts Manager (2) REG: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SamSs!Start
