The Module DLL C:\Program Files\Multi-Factor Authentication Server\pfiisnm.dll failed to load.  The data is the error.

Active Sync is down on our Exchange 2013 server but client based is working fine. This error comes up nearly ever second or so. We had Microsoft Multi-Factor Authentication Server installed initially but didn't really like it so it was removed. Now this error is popping up.
