We are getting many error 404s in our IIS log that say certain cfm and js files are not found. The program seems to work fine and no users have complained about pages not coming up. What can be the cause of these errors ?

Most people won't notice JS errors in a browser if they don't do anything important, you could easily have ajax calls to pages where no-one will see an error in a browser.

Are the pages being called part of your application? Or nonsensical ones? If they're not your pages then it could be someone scanning your site for commonly-used folders (such as /phpmyadmin) to try and see if you're using certainly packaged products they can exploit.

The error 404s for Javascript are for wddx.js and cfform.js.

The 404 errors for Coldfusion are for 2 templates that are used at least 100s of times a day. Both of them have script tags that have src equal to wddx.js.

I will ask someone about the possibility that someone is scanning etc.

Any other ideas would be appreciated.

The progam is running ok despite the errors showing up in the log.

Are those two script tagas in those two templates the ONLY fuctionality that would be making use of ColdFusion built in code.

Maybe somebody made use somewhere else in the file of a simple <cfinput...> or other tag that would use those files, but since the code "works" without the extra functionality, nobody has noticed the lacking.
