ASP NT Authentication

I am quite stuck in my newest project. It is making an online site admin application using ASP. I have figured out how to edit the files and folders I need, but now need to secure it. What I would like to do is integrate NT Authentication. I need anonymous read/execute access to the root folder of the site, and when I(admin) am logged in to the site(cookies), need read/write/modify/execute rights based on the NT Auth. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
