How do i set up openVPN server?

[jonmon6691]

I want to set up a VPN server on my personal network so i can log in with my laptop from a remote location securely. I have the windows version of openVPN and I am following the instructions to the letter but when I make the server key, it does not create server.crt like it should.

here is the output of the "build-key-server.bat server" command.
