We're setting up an ASP.NET 4.0 website on Windows Server 2008. The site uses Integrated Windows Authentication for authentication. (It does not use ASP.NET authentication or authorization.)
In IIS, we have only Windows Authentication enabled.
When we browse to the site using localhost as the host header, the site works fine. When we browse to it using the FQDN, the site prompts for username/password but doesn't accept the validly entered credentials.
Some items to note:
IE does have Integrated Windows Authentication enabled
The site with FQDN is entered in the Intranet zone in IE
We've tried adding the site to the Trusted sites to no avail
We did change the Identity on the AppPool from ApplicationPoolIndentity to Network Service with no success
We verified that IUSR has read and execute access to the directory and files
We've set NTAuthenticationProviders to both "NTLM" and "Negotiate,NTLM"
What are we missing?
Thanks.
We were informed finally that the server is not on the same domain as we had been led to believe so it couldn't authenticate against Active Directory. (We had been testing with a local account.)

I have migrated a asp.net web site from IIS6 to IIS8.5. Almost all issues are fixed. But it seems that the identity of the user gets lost.
Related questions I found:
Cannot get authentication working in IIS 8.5
Configure windows Authentication in IIS 8.5 on Windows Server 2012
Receiving login prompt using integrated windows authentication
When I open the webpage from the server IE browser there is no login prompt (which would be fine if the integrated authentication was used)
When I open the webpage from a remote client I should get a login prompt for authentication (since the user on the client does not exist on the server). But there is none.
On the old platform IE6 was used. On the new platform IE is used with compatibility mode
In the old web page integrated windows authentication (only) is enabled and working.
In the new web page on IIS 8.5 I tried all kind of settings but none seem to do the trick.
Found out that actually the authentication itself is working.
This link was very helpful finding this out:

But the user name gets lost in a different way. I will close this question and post another one.
I have not dealt with classic ASP for over 13 years (and IIS and ASP.NET for a while as well) and today I had to move a classic ASP website to a new server - Windows 2012 with IIS 8.5 from Windows Server 2003 with IIS6. I copied the website directory onto one of the drives (the same drive letter as it was on the old server) and went to IIS Manager and created an application for that directory.
Locally I can access the application via http://localhost/AppAlias/Default.asp and it renders in IE but when I access it remotely via http://ServerName/AppAlias/Default.asp, it does not rende rin IE, instead I get "Internet Explorer cannot display the webpage" error. When I open the same URL in Chrome, it renders just like it does when accessed locally.
I checked IIS settings on the server for ASP applications and under Basic Settings I clicked on Test Settings. Authentication uses Pass-through and it seemed fine but authorization had a warning mark on it. The message was "Cannot verify access to path E:\Pages\Test\AppAlias" and in details I found the following:
The server is configured to use pass-through authentication with a built-in account to access the
specified physical path. However, IIS Manager cannot verify whether the built-in account has access.
Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain,
and the application pool identity is NetworkService or LocalSystem, verify that \$
has Read access to the physical path. Then test these settings again.
I gave Network Service read access but still having an issue. Can anyone help?
i have hosted a asp.net web applciation in windows server 2008 R2,IIS 7.0 which was developed in .net framework3.5. i have given the below authentications in IIS.
while i am accessing that website from the other network ,its asking for username and password of the server.
actually it should not ask for the login without enabling the Anonymous Authentication .
You'll need to enable anonymous authentication - there's no other way to do this
Newly installed IIS on a clean windows Server 2008 R2. Installed all security option. Then for the default web site authentication, enabled windows authentication and disabled all others. Then when access the default page iisstart.htm, it should give me a popup for authentication message.
but when I access the test page like: http://localhost/iisstart.htm, there is no popup. same as enabled Anonymous Authentication.
How to fix it?
I think your webservice is accessing files via your app pool identity, remove this user from the security access list on the file.
If you go to "localhost", then IE will see this as part of the "Intranet Zone". In the "Intranet Zone", IE will by default automatically send your current credentials to sites that use "Windows Authentication".
The result is that everything is probably working correctly.
First of all make sure you check if the app pool user can access the files of the website (NTFS security settings). See: IIS7 Permissions Overview - ApplicationPoolIdentity
After that (and double checking that only Windows Authentication is enabled in IIS) take into account that your URL must not contain dots! You can make an extra binding (see: https://technet.microsoft.com/en-us/library/cc731692(v=ws.10).aspx) that contains only letters and numbers and then add that binding to your local hosts file (open a text editor as administrator and then edit the file hosts in C:\Windows\System32\drivers\etc) to check.
I'm working on a simple ASP.Net page (handler, actually) where I check the value of the LOGON_USER server variable. This works using Visual Studio's built-in web server and it works in other sites deployed to the live intranet site. But it doesn't work on the IIS instance on my local XP machine. How can I fix it, or what's going on if I can't?
What authentication do you have enabled in IIS? Anonmyous, Basic, Digest, Integrated Windows? Sounds to me like anonymous access is enabled/allowed, and nothing else. This would means that LOGON_USER is not populated.
When you access your local IIS, trying using http://127.0.0.1 in particular if you use IE. IE will recognize "localhost" as being in your local trusted zone and will automatically pass your XP login credentials through when Integrated Windows auth is enabled.
In addition to Jon's answer, IIRC even if you have Integrated Authentication enabled, if Anonymous Authentication is enabled it will take precedence...
