OpenVPN istallation and compatability

Hello all, I'm new here but found a lot of interesting stuff already.

I am in the process of rolling out Vista Business machines our users who need OpenVPN access to connect to our network from home.

I have installed VPN and done all of the relevant certificate requirements which allow access into the network, but my only problems is that I cannot get the program file to run at start up.

By doing this all they have to do is double click on the icon on the taskbar to launch the connection. Without this, they have to run as administrator from the desktop and then double click the icon, which most people forget.

I added it as a scheduled task to run at start up but it looks like its doing nothing. However, if I view the same scheduled task and run it manually the program starts. Any ideas?
