Page cannot be displayed in release mode

[Joel]

Hi,

I am pretty new to asp.net, and have recently taken over a project. I have
gotten to the point where I am about to release my changes, but for some
reason when i build the project in release mode and launch in in IE I always
get a "The Page cannot be displayed" page instead of my login form.

Anyone have any ideas? The application works fine in debug mode, its just in
release mode that this happens.

Regards,
Joel
