If the line I mentioned above in your web.config is uncommented then it's going to hit OnAuthenticateRequest. It's part of the httpModule request. It's in OnAuthenticateRequest that the redirection to WindowsSignin happens.

Do me a favor. Send me (mhorton@telus.net)  your web.config with anything relating to your connection strings/user credentials **** out.

At this point I'm out of ideas as I can't replicate the problem. I do know that Eric (wilz) is planning on trying to do some debugging on his end and one of us will report here on what we find.

Hi Ben

When you look at the original web.config the section you're talking about it looks like this:

<!--       <identity impersonate="true"/>       <authentication mode="Windows">       </authentication>   -->

To uncomment just the <identitiy impersonate="true"/> just move the initial <!-- down so that it's in front of <authentication="Windows"> like this:

<identity impersonate="true"/>     <!--       <authentication mode="Windows">       </authentication>   -->

Thus the <identity impersonate="true"/> line is now uncommented.
