Does anyone know of popular Drupal sites "in the wild" running on IIS, or even Apache/Windows?
I'm building an internal application at work and am forced to run on Windows Server VMs. From the experimentation and research I've done, Drupal runs fine on IIS but I have no experience or idea what will happen when we start to get hundreds of concurrent authenticated users. I'm more comfortable scaling Apache, but I haven't done it on Windows.
Any experiences or stories would be appreciated. Thanks!
