Been thinking a bit.
If these happens because of lack of permissions you'd get a 401, not 404. Have you double checked the IIS bindings and logs to verify that you're actually reaching the correct site?
If the default.html residers in the same folder as /json I don't see how this would occur. If you find the issue, please let me know the root cause so others can be helped (or to satisfy my curiosity :))?
