Okay I have narrowed things down a bit. Apparentyly IIS automatically converts the entities. Looking at the detailed error report the requested url displayed is correct (it got converted properly). The module reporting the error is IIS Web Core and the Notification is the MapRequestHandler and the Handler is StaticFile.

So for some reason it looks like when there are entities in the url after the conversion the php handler mapping is skipped and it goes straight to the staticfile handler. IIS is not recognizing the php file extension for some reason and doesn't use the correct mapping and I have no idea why...
