Problem with IIS Windows Authentication using IIS10. IIS log shows error 401 2 5 codes.

I have a web application developed in .NET 4.5.2 deployed on IIS10. There is an XML file set with Windows Authentication and disabled all other authentication rules. My problem is when I access the XML file through the browser it shows the credential pop-up window. I enter the correct password but the pop-up keeps appearing asking for credentials even though I enter correct credentials. I enabled the IIS logging and get the 401 2 5 codes. The application is added int trusted site but still getting the same error.

The application works fine on all other clients except one.

Please help me diagnose the issue.
