>> Now I'm getting a login prompt for the server on which the app is hosted
Did you mean you access the web app from your own computer? If so, will you get error if you enter your domain account and password?
Will you get any error if you access the web application from Windows 2008 R2 Server?
In my option, when you access the app which enables Windows Authentication on Windows 2008 R2 Server from external computer, you need to provide user name and password to bypass the login prompt.
