title: How to add users for windows authentication / IIS
body: <p>I'm porting a legacy (read ancient) .asp application to a new server for backup purposes. It uses this code to determine the user:</p>
  
  <p>sLogonUser = LCase(Request.ServerVariables("LOGON_USER"))</p>
  
  <p>I believe in order for this field to be populated, I've got to turn on "Windows Integratged Authentication" using IIS Manager. I've done this, but now I get an error message stating "The website cannot be displayed". I think this must have to do with authentication, because even a simple "hello.asp" has the same problem. </p>
  
  <p>This leads me to believe that valid windows users have to be registered on the new server. Is this "Active Directory"? What's the best way to go about adding users? </p>
