I assume this is an IIS error, as this doesn't happen if I run the project on my local machine.

I have my stylesheets at ~/Content/css

Any files in that directory won't load on the page, and when I navigate to them directly, I get a server error:

401 - Unauthorized: Access is denied due to invalid credentials.

You do not have permission to view this directory or page using the credentials that you supplied.

This only happens with that directory, I have no problem accessing any other files. Is there something I need to do in IIS7 to stop this?

  1. Open IIS and select site that is causing 401
  2. Select Authentication property in IIS Header
  3. Select Anonymous Authentication
  4. Right click on it, select Edit and choose Application pool identity
  5. Restart site and it should work
