no, im not on shared hosting, I own my own server. Using IIS but somehow thing that when CF was set up it was set as a standalone server.
but in any case,
I went into IIS and switched the 404 form c:\winnt\.. to the page I wanted to display, then stopped and restarted the server and refreshed it...
Then in CF administrator, I added the relative path for Site-wide Error Handler to my error.cfm file
Still not displaying my file, just the default
