The administrative web site does not work

After installing Content Studio the web site works as expected but the administrative web site displays "The page cannot be displayed" and no login dialog is displayed. I know that the url:s are correct and in IIS manager I can see the administrative files in the virtual directory created under my web site.

This error can occur if the network environment prevents IIS Integrated Security from working. During installation a Content Studio Web site is set up with Anonymous access disabled on the admin site and enabled on the site and the authentication method is set to Integrated Security only.

Try to change the authentication mechanism to Basic Clear Text and uncheck the Integrated security on the admin site AND on the site itself. When you change these settings on the main site you will be IIS manager asks if the settings should be propagated down to the sub site but just Cancel this dialog.
