>The only problem is you shut down all services and in production mode that is a problem if you have multiple applications running. Are you saying there is no way to shut down just one com server with out shutting them all down unless you use MTS?

Frank,
Correct. Instead of IISAdmin having access to all your COM objects, it simply gets a proxy object. MTS/COM+ holds and controls the actual object. It offers the interface to shut down individual objects as needed. It adds the extra layer of abstraction which is a slight performance hit, but it gives you the ultimate in flexibility and maintainability because of it.

IIS has no interface to get to the things it instantiates in memory. You have to make it release everything in memory.
