 <p>I am dealing with exactly the same problem, but my setting is allready on 'Windows' but I can not get it to work properly.</p> <p>Changing the settings here (ASP.Net Configuration for Website), result in invalid connectionstrings, because it is not writing the web.config well. Can you tell me if your web.config changed after changing this setting ("None" to "Windows")? Do you know if your provider has had these problems before?</p>
