Question

HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials.

Asked by: dragy

Hi,
I'v created web application and want to host it on IIS 6.0 configured on Windows Server 2003 Enterprise Edition. Server is on domen (OPERATORS). I'v disabled anonymous access on secyrity tab and I'v chacked Integrated Windows authentication. There are 20 computers accessing this server and using this application.  When they browse app login window appears. On 17 of 20 computers login process pass ok using account from OPERATORS domen, but on 3 computers it's impossible to log in on application. The strange is that these 3 computers (and all 20) can log in on another app hosted on the same server with (I think) the same IIS configuration.
The error these 3 comps get is:
HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials.
Internet Information Services (IIS)

What could be the problem?

Thanks in advanced.

Sounds to me like these users do not have permissions to access the filesystem on your web server. Check the NTFS permissions to the website path and make sure that these users are defined for access either by a group assignment, or with their AD account explicitly.

Thanks ajarvey for your reply,
the strange thing is that I can't login on app from 3 computers on any domen account (domen user), but I can do this from the other 17 pcs. I choose domen admin and try to login, but it's not successful.
When I try to login on another app in the same server (domen), it's ok.

Excuse me, I' wrong. I can't login to any application on OPERATORS domen from these three comps, using any domen user account of this domen. If I set Automatic logon ... it's ok, but I need login. This happens in both Intranet zone and Trusted sites. It seems that these three computers have some problems with this domen. I can login on sites on another server (under W Xp) which is on domen USERS. Domen OPERATORS i sunder W Server 2003 Enterprise Edition.

I don't know why does it happen but I have solved it by disableing anonymous access and setting authentication mode on Basic, choosing Default domen on the IIS server. In web.config file of app it should be added a tag
