Windows prompts for login but using Forms Authentication

Hi all,

I have an ASP.Net application that has worked swell on both my
development environment and production for some time now. Development
is running on a WinXP Pro box, Production is running on a Win 2000
Server.

However, the other day we had to move the application to another
server. The new server is Windows 2003 box.

The problem is that when you visit any page that requires forms
authorization IE will prompt the user to log in to that box. This
doesn't make sense since I'm not using Windows Authentication, I'm
using Forms Authentication.

For the heck of it, I went to IIS and checked. Anonymous authentication
is enabled, and all other forms are disabled. That includes Windows
Integrated and Basic.

Then for the heck of it, I made sure that the local "ASPNET" account
had full control on every single file and folder on that box. Just in
case it's some ACL permission issue.

Still, the browser prompts for logon.

What is strange is, when you click cancel on the logon prompt, it still
lets you in and the page runs. But as soon as you try to access another
page, IE prompts you again to log on.

One thing though, the app works fine if I VPN in to the network, and
access it via IP address instead of using the web domain name assigned
to the app in the DNS.

This gives me a clue that it could have something to do with our ISA
server. Or perhaps DNS?

Has anyone else had this problem? How did you fix it?

Turn anonymous on in IIS.
