Cloned VM redirecting to original hostname

Hello,

I recently cloned our QA web server inorder to make a DEV environment. After I cloned the web and database VM's I updated any reference to the original qa-web name to dev-web. In IIS I updated the site name and the .conf files but anytime I try to access dev-web the site automatically redirects to qa-web. 

Is there a step that I am missing, or some other config that needs to be updated?

Thanks,

Avery
