IIS Security strange things

I have intranet application based on ASP.NET on Win2000AS (Framework 1.1).

Website uses an Integrated Windows Authentication as Authentication method
in IIS and has following security configuration in the web.config

------------------------------------------
<identity impersonate="fa lse" />

<authenticati on mode="Windows" />
<authorizatio n>
<deny users="?" />
</authorization>

<customErrors defaultRedirect ="CustomError.a spx" mode="Off">
<error statusCode="401 " redirect="Custo m401.html"/>
</customErrors>
------------------------------------------

And everything goes fine for 99.9% users and not for one only, who always
get a popup login window to login this website.
He has WinXP box, with latest browser, like many others, but for any reason
website cannot recognize that user as a valid internal user.

Any ideas? Thank you

Hi ,
In IE open Options -> select Security
Select Custom LEVEL -> User Authentication
Check if the user has checked Prompt for user name and password.
If its marked make it to auttomatic login only in intranet zone.

Hi, Arvind

yes, he has the default level (medium low) for the intranet zone
and in addition that site inserted in Local Intranet Site List
(Security - Sites - Advanced...)

Why is it advisable to place scripts which contain details of your login and password outside of the publicly accessible web area on your server. Surely if the files that contain the details are given a php extension then no-one can get at the information contained by these files even if they point their browsers directly at the correct named file, because apache will parse the php file before it is sent. i.e.

S**t for brains strikes again! Why did I do that? When I met the clients and at some point they vaguely asked whether eventually would it be possible to have some people who could read the data and some who couldn't but that it wasn't important right now. And I said, 'sure, we can do that later'. So now I've developed an app without any thought to security and am trying to apply it afterwards. Doh!, doh! and triple doh!

For most users, this new feature is actually very convenient. If you want to control the update process,...
