ColdFusion admin password does not work after fresh install

I have recently installed ColdFusion 2016 on Windows Server 2016. During the first install, I set a custom admin name (cf_admin) during the install process. I was not able to log into the Admin Portal once the installation finished (invalid username or password). I tried using the password reset batch file as well as uninstalling and re-installing. Every time has been the same result. On subsequent installs, I left the default "admin" name in.

I installed on another server and left the "admin" name in on the first go and it seems to be working fine. Is there some file or setting that is left behind after uninstallation?
