windows authentication box not opening

I have a web site that requires Windows Authentication for the users to be able to view. If users don't login properly they are directed to a page that tells them they don't have permission to view, etc...

I have one user who goes to the site and it automatically redirects them to the "no permission" page without even popping up the windows authentication dialog box. The user is never asked to enter a user name and password. I had her check the User Authentication settings in IE and it seemed to be set correctly (i.e. not set to anonymous login). I still believe it is a setting on the user's IE, but I don't know where else to look. Could it be a pop-up blocker setting? Her company has removed the option for her to change pop-up settings. Would this be an issue? I wouldn't think so, but just a thought. Is there another setting that we need to look at?

I would check out the server running the web site.  Is it IIS?  If so, look at the properties and make sure Windows Authentication is checked and see if anything has changed.  


This is what you needto do:
Uncheck Anonymous authentication 'and' make sure "Integrated authentication" is checked along with Basic.

In intranet, IE passes along the user's username/password to IIS and does not prompt for username password. You can disable this feature to test the iis authentication. go to Internet explorer, tools, options, then security and Advanced, it's the last potion.
