I&#039;m trying to get Server.Variables("Logon_user") to work.<BR>I removed anonymous access from the subsite I&#039;m on and now, instead of using NT Authentication to Active Directory, the site requests the user to log on to the Web Server itself.<BR>How do I get user authentication via NT Authentication if the user logs on from a machine that is authenticated to active directory but to use basic authentication if on a machine that is not logged on to active directory (in some cases, the user logging on might not have an Active Directory account).
