Classic ASP on IIS7: refusing to send errors to browser on 500 Internal Server Error

I have classic ASP running on IIS 7.

Even though I configured the ASP "Debugging Properties" to "Send Errors to Browser = True", the web app REFUSES to send errors to the browser and continues to send a 500 internal server error.

  • My browser has "Show Friendly HTTP Error Messages" unchecked.
  • Failed Request Tracing is installed (not sure if that's related)
  • Happens both on web pages loaded locally on the server and remotely
  • The App Pool is integrated (not sure if that matters)

Any ideas?
