Less then two network interfaces were detected on this machine. For standard VPN server configuration at least two network interfaces need to be installed. Please use the custom configuration path instead. This server has two interfaces. What's the deal? Windows 2003R1 64bit Dell 1950.

Verify the user account logged onto the server has admin privilege. And make sure the two NICs are enabled and both of them have IP address configured. Tim CHENGod Bless!
