Hello Aegis,
Thank you for the reply.
/404index.cfm does exists in the website root folder.
When accessing the URL, http://www.websitename.com/404index.cfm directly it does work.
But when I put this URL (only /404index.cfm) in 404 error pages section and execute a 404 URL like http://www.website.com/hello.cfm, it gives me a blank page. This is the same case for any .cfm file that is mentioned in 404 error page section of IIS. I created a test cfm file just to see if there is any coding issue with 404index.cfm.
Any ideas?
Regards,
Kurian.
