This works fine on my localhost but uploading to re-invent it does not work.

1. On the web host in the web.config you must have authentication set to Forms.

2. You must then provide a login screen.

3. Working on your own local host you do not need this and can leave authentication set to windows

4. I realize that on a webhost you would always need to have a login screen especially dealing with web parts
