title: IIS settings for mvc application using Windows Authentication
body: <p>I have developed an MVC intranet application which I have successfully deployed to IIS.</p>
  
  <p>I have enabled Windows Authentication and denied access to anonymous users, however, only some accounts on the domain are able to gain access to the application.</p>
  
  <p>I have checked these accounts and there is nothing special about them that I can see.</p>
  
  <p>The first check for security is Domain Users which everyone is a member of.</p>
  
  <p>All other users are prompted to login but it does not recognize their credentials.</p>
  
  <p>I get a 401.1 - Unauthorized Error</p>
  
  <p>Not sure what else to try. Any suggestions would be appreciated.</p>
