I have run into some sort of security related problem while migrating a WC application from my development server to the production server.

There must be something about the production machine's setup that is different somehow from my development server which I do not understand. The machine was set up by another individual and it's configuration is not exactly like the development server. Specifically, on the development server my virtual directories are under the Default Web Site but on the production machine the virtual directories are under a different web site set up on the machine. The physical and virtual directories were all created on the production machine and populated with the application files. I set up the directories and security permissions as close to the development server properties as I could and since I am using Windows NT Challenge/Response for the IIS security settings on the directories and files, like on the development server, as long as a user is logged onto the Domain, they should be granted transparent access by IIS to the web pages. If they are not, then a challenge for userid/password should be issued by IIS automatically, but this is not happening. IIS is challenging me on every attempt to access the pages even tho I am properly logged onto the Domain.

Strangely, when I hit the main page, IIS prompts for userid, password and domain and when I enter my data it allows me into the page. When I then try to access a secondary page from a link on the main page, the IIS prompt is displayed again but it rejects my data at this point.

For some reason IIS does not recognize me as logged in with a valid Windows NT Domain account.

At this point I have looked at every setting I know to look at so I am stumped as to what is causing this. What am I missing here?

Thanks,
Bill
