Just upgraded to OS X Yosemite (10.10) and found the PPTP VPN becomes not working. Well the PPTP VPN does get connected successfully but the problem is my office file servers become unreachable due to "unknow host" error unless I use their IP addresses instead of the host names. When I ping their host names I got the error:
Cannot resolve server.company.local : unknown host
I checked the DNS for the PPTP VPN, it is with two of my DNS servers in place and looks just fine. Again, it was working well before the upgrade. Can you help please?
