And it used to work! After re-creating my site with a fresh copy of my local version, and a freshly made connection to my site through IIS v7, I now get the following message: ****************START_ERROR_MESSAGE*********************** Server Error in '/' Application. -------------------------------------------------------------------------------- Security Exception Description: The application attempted to perform an operation not allowed by the security policy.

Does anyone know what I'm missing, or what I can do to pinpoiint where the error lies? Thanks, Jack Webb
AHA! I found it! I needed some authority, i.e. <trust level="High" /> in the <system.web></system.web> section of web.config. Although I still don't understand why I didn't have this problem before. And also whether or not what I did to fix it is the correct thing to do. So, I still would appreciate some thoughts on the subject. Thanks, JJW
The trust level value is stored in your applications web.config file. If you set it before but uploaded a new web.config file, the value may have gotten over written.
