Problems with PPTP VPN server authentication - Could not retrieve key agent account information

Errr so far switching to a mac based server has been a mess. I have had it with permission issues!!

Here is my latest problem. After rebuilding the server several times my VPN clients can't connect. Every other time it has been fine but for some reason its just not working. I did recreate the vpn from a back up. I am not sure if that has anything to do with it. Anyway below is the error I am getting. Anyone have any idea what is causing it? You have all already been so helpful. Thank you very much!
