Hi!
In web.config There's a setting about directory or folder mode that is used to remove the extension. For this to work you'll need to activate wildcard mapping in IIS as well.
If you don't want flat urls make the setting in web.config is disabled and them republish the entire site. It might even be necessary to first unpublish and then republish all content again...
