I have a Windows Server 2003 box that I would like to configure PPTP VPN on. It is behind a firewall. That firewall's rules are configured properly to allow traffic to pass through.
I am following this guide:
Whenever I finish with the first stage (after enabling VPN on the internal NIC of the Windows Server), the connection breaks (broke access to all outside services: SMTP, IMAP, Terminal Services, etc) and I can not access the machine without having console access, which, as I am not onsite, I do not have. I had to have an onsite user manually get on the machine and remove the new RRAS VPN connection on the internal NIC so I could re-access the machine.
How do you enable VPN through RRAS on a Windows Server 2003 machine without temporarily breaking access to the machine?
