Forms Authentication Default Document Not Redirecting. Please help I am going mad

Hello all,

This is driving me absolutely nuts and I have spent a day and a half on it tried misc configurations and googling the problem for hours.

Using Forms Authentication on IIS7, Framework 4.0. Everything seems to be working fine when I go directly to home page or

http://www.rewardroster.com/Default.aspx

but if I go directly to :

http://www.rewardroster.com

the forms authentication redirects me to

http://www.rewardroster.com/Login.aspx?ReturnUrl=/

I removed forms Authentication and then the default document does work so its not an issue with the default document. I have tried multiple things here is how my current web.config looks:

Code:

 <authentication mode="Forms">
        <forms name="appNameAuth" loginUrl="Login.aspx" protection="All" timeout="60" slidingExpiration="true" defaultUrl="Default.aspx" path="/">
        </forms>

WITH

Code:

<location path="Default.aspx">
		<system.web>
			<authorization>
        <allow users="*"/>
        <allow users="?"/>
      </authorization>
		</system.web>
	</location>

Does anyone have any ideas on this?? I would SINCERELY appreciate any clues. Thanks for your time
