Windows – Automate setup of Win7 VPN, including registry settings and security policy changes

vpnwindows

After numerous difficulties I have managed to get a Windows 7 machine to connect to OSX Server's VPN. I am looking to automate the setup process for Win 7 clients, which would include:

  1. add one registry key
  2. change couple security policy settings
  3. configure a VPN connection (import a VPN profile??)

First 2 items above are per OS X Server: How to connect to VPN service from Windows article.

Is there a way to automate the setup so it is a single operation that can be performed by the user as opposed to me having to walk through all the steps on every machine?
