Hi Jay,

We also had difficulties with opaque "Application Error" screens on some of
our controller actions and not others when running as a service.  The 
only hammer
I have to hit this screen is permission problems, so we edited the service
"Properties -> Log On -> Log on as: " property
to be a different, slightly more powerful, but not too powerful, account.
This may only help you if your app is accessing files and other
windows resources.

Sorry to not be more specific, we're not exactly sure whats aggravating
using the default service settings either.  You're question was a good one.

The win32 support is much appreciated, thanks a lot Luis Lavena!
