Hi Daniel,

I do not think you can do what you want. To get the NT username, you must
turn off Anonymous Access on your Web site (either manually using IIS Admin
Console or programmatically); otherwise, all users will be anonymous
irrespective of whether they are logged onto domain or not. If you do this,
then the users who are not logged onto the domain (or coming from Netscape
browser), will be presented the ugly login box (Basic authentication). They
can use the Basic authentication dialog box to login, but it does not seem
like what you want. It would be really nice if you could programmatically
detect whether the user is a domain user or not and let your Web application
to behave accordingly from the ASP or ASPX logic, but I do not think it is
possible.
