title: IIS7 (Windows) Authentication -- Cannot figure out why new website errors 401
body: <p>I am trying to make a new website on an IIS server, of which has websites that are using Windows Authentication just fine.  However, for the life of me, I cannot figure out why my new website refuses access (401.2)</p>
  
  <p>Basically, I create a new website and add a single .html file ("Hello, World").  I can access it just fine.  But turn off Anonymous, leaving on Windows Authentication, I get prompted for ID/PWD, ending always a 401.2</p>
  
  <p>So, I decided to make a new website as a copy of the existing working website on the same webserver.  I've even gone and made the new website share the same App Pool and the same Physical Path.  This way, as far as I can tell, the only possible differences between the two websites is now the IIS configuration of the two sites.  Still can't authenticate.</p>
  
  <p>I've switched the bindings, doesn't help.</p>
  
  <p>I've even compared the settings in applicationHost.config, making sure they're equal.</p>
  
  <p>Any ideas?  Thanks in advance.</p>
