IIS 7.5, Win2008 Server R2 - 401 - Unauthorized: Access is denied due to invalid credentials.

Hi,

I'm setting up my first site on IIS 7.5.7600.16385 on Windows 2008 Server R2 Standard, and for some odd reason I'm the only user that can authenticate to the site. All other users get the "401 - Unauthorized: Access is denied due to invalid credentials" error message.

401 Error Message

Folders settings showing everyone has access.

Any ideas what I'm missing?

Thanks.
