Can't disable Windows Authentication? [SOLVED]

Hello, We enabled Windows Authentication for our development website a few weeks ago.

Now, after I disable it, the site shows only the 401 page:

Quote:

401 - Unauthorized: Access is denied due to invalid credentials.

It doesn't offer a login box. It doesn't do anything no matter what URL you try to load, including the home index page, except show that 401 message.
I disabled Windows Authentication on the website and on the server. What could I be missing?

CLARIFICATION:

I disabled Windows Authentication through the IIS Administration plug-in in Administrative Tools. I disabled it at the server level and at the website level. If this is being caused by an overlooked application setting, which would that be?

SOLUTION:

While I disabled Windows Authentication, I failed to re-enable Anonymous Authentication. Doh! Now it works.
