There's quite a few leads in this Google search :

et%22+%22active+directory%22

The first link returned is :

There's good tips in this article :

======================================

You can use IIS Admin to require Windows Authentication for a Virtual
Directory or other Directory (turn off Anonymous access)

Browser will supply login credentials of user running browser (note
there are Internet Explorer security options that modify this
behaviour)
(I do not think Firefox can do NTLM Authentication - but I could be
wrong)

Now your Web Application can determine who is logged in using the
LOGON_USER server variable

Debugging security access can be done with a combination of Event
Viewer, setting Local Security Policy auditing options and using
sysinternals TokenMon

Consider using custom error page in event of authentication problems -
explain about Firefox and IE security options etc.
