SOrry...i meant i do not want to allow anonymous..i only want to use Challenge and Response..but i do not want that NT login Window to appear everytime, someone hits the intranet....it only does this on my main webserver..not on my test machines...does anyone one know why?
Make sure you don't have both Basic Auth. and Challenge/Response turned on. Aslo, check to make sure you are using the correct domain. If you are using only Challenge/Response, the user will not get a login screen if he or she is already logged into the domain you are using to validate the user id's.
