I’m currently playing with Connection Manager Administration Kit for Server 2008.
Why? Because with the advent of Windows 7 (and Vista, to a certain extent), it’s a complete pain in the butt to programme a tool like AutoIT to script and automate the configuration of a VPN connection for our end users. The key issue, is that Microsoft don’t seem to provide any “command line” shortcuts through things like DLLs or Shell extensions to quickly bring up the “Set up a new connection or network” wizard. Sad face.
