HTTP Error 403 - Forbidden

I've been playing around with VWD 2005 Express and when I "View in Browser" with IE, everything works fine.  But when I try to "View in Browser" with FireFox, I get a HTTP authentication prompt and then I get the following message:

Server Error in '/TestParts' Application.
HTTP Error 403 - Forbidden.
Version Information: ASP.NET Development Server 8.0.0.0

I've tried entering USER and MACHINE\USER local accounts and still get 403 Forbidden -- any ideas

    It's an issue with NTLM Authentication.
    1. Right-click on your solution in the Solution Explorer.
    2. Select Property Pages.
    3. Select Start Options in the dialog that opens.
    4. In the Server section, uncheck NTLM Authentication.
    That did the trick for me. :)

    Solution Explorer is one of the windows inside of Visual Web Developer. Normaly it is located in the upper right corner. You can also jump to it by pressing Ctrl+Alt+L from within the VWD. It's just a window that shows you files that make up your web site.

    Alternatively, you can just use "Website > Start Options..." menu item.

    I have the same problem. Except that the site was displaying fine. Then I left for a meeting and when I came back and did a refresh I got the error message. To my knowledge, nothing was changed.
