Pass-through authentication failing

Question

The enviroment:
Server A: Windows Server 2008 R2 / IIS 7
Server B: Windows Server 2003 R2
Domain Controller: Windows Server 2003 R2
Both server A and B are part of the same domain.
The issue:
We have files stored in server B that are being shared as \\B\Files. We want to have a virtual directory/application in IIS on server A to make those files available on a web browser,
but, we want access to be controlled by NTFS permissions, and access granted to the user accessing the website by pass-through authentication (challenged for user and password by the browser).
We have set up an application pool, and have set the identity of it to a user that has
read NTFS permissions to \\B\Files. We then set up an Application and set its application pool to the one mentioned above, and have pointed it physical location to \\B\Files. In the advanced settings, we set the physical path credentials
to Application user (pass-though authentication).
In the authentication settings for the application, we disabled all but Windows Authentication, and in the providers, we have removed everything but NTLM, which is the one we want.
When we test it (https://serverb.com/Files) however, we are challenged (user/password prompt comes up) as expected, but despite what we put in, the prompt comes back, as if the user/password was wrong, or as if the user did not have enough permissions
to access the files. We checked permissions and that's not it. And we have also checked the domain controller to see if the request is getting there, and it is, which means that it is authenticating properly. We can only assume there is a communication
problem, or restriction somewhere.
We are not sure where else to look, and any ideas would be greatly appreciated.
Thank you

Since this is really an IIS question you should post to the official IIS
