ASP.NET Windows Authentication prompting for credentials for just one user

I'm using WindowsIdentity.GetCurrent() to retrieve user information. I want this to happen automatically without the user being prompted by their browser for credentials.

In IIS, I have ASP.NET impersonation and Windows Authentication enabled and then Anonymous Authentication disabled:

IIS Authentication settings

This has been working to silently retrieve user details in this application for 3 years. Yesterday, however, a single user started getting prompted for credentials in all browsers.

Is there an AD issue or a browser setting that can force a prompt rather than automatically passing credentials like everyone else? What could their issue be?

if there is a new issue then probably must be with only one browser - do you have check that with different browsers ? eg I have notice that google chrome stop redirect http page to https when its inside iframe and miss the cookies... but only chrome. – Aristos
@Aristos - I have confirmed that this happens in all major browsers. Simply resetting or reinstalling the browser hasn't fixed the issue. – TheIronCheek

We finally discovered that there was something wrong with the user's profile on the machine. We wiped the profile and set it back up again and it works and intended now.
