Using FireFox 1.0 on new ASP.NET projects brings up authentication dialog when there should be none

[~~~ .NET Ed ~~~]

This is a strange problem and I wonder if anybody has experienced this
annoying anomaly.

I created a new ASP.NET project with its web-shared directory on my WinXP
Pro/IIS machine. I compile the project and everything is fine so far.

Accessing the default page with Internet Explorer 6.0 shows the page as
expected. I am however using FireFox as my browser (don't ask why). Using
FireFox 1.0 on the new ASP.NET project brings up an authentication dialog:

Please enter username and password for "" on
http://localhost/MyWebProject.

Now that is odd because the page in question (nor any of those within the
project) request user authentication.

However, I know that after some use (how much it depends) under some random
circumstances, the project works fine with both browsers.

I submitted a but to the FireFox team, but I am sure there is *something* in
the newly created web applications (default settings) that make the other
browser get confused. I want to know what that is because at the moment I am
investigating a rendering issue so I need to have the project operational
with both IE and FireFox.

Thanks

Check IIS. Do you have "integrated auth" turned on? Dont think that FF
supports it, only IE.

Thanks a Million Curt! I had just noticed that I was getting these two
headers in the response (used dHTTP utility)

WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM

That did not affect IE, but caused FF to stumble to its knees. I checked the
local web share in question and indeed it had (seems to be the default)
Integrated Authentication option checked. I disabled and enabled anonymous
access and now it is fine.

Thanks!
