[coldbox-5.2.0+791-201810172328] Issue copying website to dev server

I have been working on a local copy of coldbox 5 creating a new site. Everything is working great on my local machine using commandbox with adobe cf11 and also cf2016. We have a dev server that has cf 10 and cf 11 installed. We have multiple sites but they use a central copy of coldbox 4.2. The cf server has coldbox/ mapped to that copy located at d:\www\coldbox_4.2.0

First, I removed the mapping in cfServer and then I copied up my website folder and went through the steps of mapping coldbox using application.cfc after it complained about not finding the coldbox mapping. Now when I go to the homepage, because of security rules, it redirects to security/login and I get a 404 instead of the security handler processing the request and rendering the appropriate view. It appears that the handler is not intercepting the request and IIS is trying to literally server a page from that folder. What am I doing wrong?

Best Regards!
