Hi, how do you try to log in? Do you type the username manually or click on the demo login link?
Have you changed the default domain? If yes, it is possible that the admin will have to log in by 'builtin\admin' instead of just the user name.
What are the IIS site settings? Is it possible that the IIS site expects
? If yes, please try to change that to anonymous.
Is it possible that you try to access your fresh install through another url than localhost
? Because in that case the portal may registered the default site as a windows authentication site. In this case you will have to change the url settings
in web.config temporarily, see
