Here is a way we can be consistent with our setup of VPN connections on computers.
Using PowerShell this is made simple with a small script on a USB stick, network share or whatever method you choose to get the to the client machine
The following is a one line PowerShell command:
Add-VpnConnection -Name "VPN Connection Name" -ServerAddress <vpn-server-name-here> -TunnelType Automatic -EncryptionLevel Required -AuthenticationMethod MSChapv2 -SplitTunneling -AllUserConnection -RememberCredential
Next is to see if this can be placed in a group policy to have it automated on end user computers
I hope this helps your process of machine setups.
