I remember running IIS and Apache side-by-side many years ago, and oh boy, was IIS a pain. Instead of a single config dir where you just deploy the configs and you are done, IIS settings were all over the registry. And don't forget component registration - a single, global registry per machine, used by IIS. Want to run staging and dev server on same machine? Tough luck. Random software installs can upgrade components and cause failures in completely unrelated failures...
