I have one website that uses windows authentication for sso. On this site I have isapi filter that checks if user is local or external. If he's local then ok. but external users get login dialog. I do not want that. Is it possible to give for all externall users some local account, that windows authentication will accept?
internet visitors use the generic IUSR web user. try giving that user access to your file/files/directories that you want to grant anonymous access to. vg
