chuckstefen,
There is little way of knowing for sure without seeing code for the entire site, which is not really possible via forum posts. Depending on how the site was architected, the credentials could be stored anywhere in the code files (and possibly in multiple places). However, since ColdFusion code is generally stored in "plain text" files, you can use any text file search tools to look for instances of the old credentials (maybe a user name or such). That will at least get you started, and help determine if the credentials are stored in only one place in the code (ideally) or multiple places (not great, but still workable).
