Symptom: Web Application always in "Loading" status and never ends.

If manually restart the UWS Service or restart the machine, then the web application can be access but only ONCE, and then will enter "Loading" issue again.

Our Web Application is accessing the Microsoft Access database using the Microsoft Access Database Engine.

This issue can only be address by moving to IIS. Anyone here got any idea? Thanks!

NOTE: Tried repair, re-install, change database, cannot resolve the problem, and it happens on multiple servers.

The most likely cause of the problem you are observing is application itself is misbehaving. Specifically, if application modifies its web.config file, or its bin folder on start up, that will cause ASP.net to unload and reload the application, which runs application start up again, which may modify the web.config, which in turn makes ASP.NET reload the etc, hence the infinite loop of "Loading".

If you navigate to http://localhost:7756/ on the machine where UWS is installed, and see a web page with ASP.NET settings, then UWS is install and functioning correctly.

Please look at the Windows Event Log (Application) to see whether any errors are logged there. For more details on how to troubleshoot issues, please refer to
