I have been trying to find out a way to let user login to my asp application
with NT challenge and response authentication.  I want to develop my own
login screen on the web and not go through the windows login screen.  There
are lots of sampel codes on how to write codes to perform authentication
with other user database... but how does it work with NT SAM???

Can someone please help or point me to the right direction.

Thanks in advance.
