The Service Control Manager can detect a failed (correctly written) service, i.e. the death of a service process without it having returned a SERVICE_STOPPED status or a SERVICE_STOPPED status with a SERVICE_STATUS containing a win32 error code - this is what the Recovery tab does.

You can access this programmatically via the ChangeServiceConfig2() + SERVICE_CONFIG_FAILURE_ACTIONS and then configure it via SERVICE_FAILURE_ACTIONS to say execute an external process.

There is no built-in mechanism in the Windows to determine service termination reason. SCM will report an error if service is unable to start, however if service has been started - any failure reporting is its own business. So if service has been terminated due to the internal errors, killed through the Task Manager, or stopped wia SCM - it will have the same status Service stopped. If services you are trying to monitor has no error/status reporting mechanism, you will be unable to determine its termination reasons.
