The problem is that I do
have permission to read the file. As I pointed out above, I can use IE to view the page without a prompt for a password or an error. In your case, you're probably using NTCR and basic authentication. In my case, the page does not provide basic authentication. That's not something I can control
PS - To those who have downvoted this, it would be nice if you explained youself. If I'm not understanding how to force IIS to use basic authentication when it's configured NOT to use basic authentication, let me know. I'm sure there's a lot of people who would love to know how to do this seeing as though you can't use Netscape to view pages that are set up to JUST use NT Challenege Response Authentication.
