>Thanks for sharing all of this info. Our setup is different since we aren't using MTS and COM+ and we are just using dbfs - so it's probably better suited to ComReturnError.

I think you have some misinformation. There are valid reasons to use MTS/COM+ in your situation. The component will run in MTS/COM+ memory, not IIS. This means you don't have to down the web server to update components. You also won't crash the web server is the component crashes.
