Notification to Application from a crashing windows service

I have a .Net application which manages a number of long running services. Some of the services occasionally crash with the dreaded

Fatal Execution Engine Error

due (I believe) to badly written unmanaged class libraries.

I'd like to know is there a way for the service manager app to receive a notification somehow that the service has crashed and stopped?

I know I can check the list of services to see are they all there regularly but I'd like to know if there is a better way to do it.
