I had a very weird problem today. I downloaded a CSS menu from http://13styles.com and no matter what I did I could not get the GIF images to display (using IIS7 on windows 7), all I got was "HTTP Error 401.3 – Unauthorized".
I checked the file and folder permissions, nothing wrong there and permissions were fine, authentication in IIS was fine, I was stumped.
After much head scratching I finally decided to check the file attribute properties and discovered the cause.
The "Encrypt contents to secure data" option was checked. Unchecking this and re-saving solved the problem.
It seems I must have enabled encryption on my drives at some point, and even though it is now disabled, new files are still being created with this option enabled, which obviously plays havok with images on web pages.
Anyway hopefully this may help others from a lot of head scratching over this one.
