Remote Desktop

Hi. We have purchased Pi 2 devices, to use for RDP into terminal services.

Have installed rdesktop, and can get this working from terminal, all is good.
The devices will go into a warehouse, we don’t want the users to see anything other than a DRP login screen when they switch the Pi on (like a thin client).

Have found information to making this autorun, but can’t find a page that explains everything.
If there a complete guide anywhere on how to do this.

Thanks everyone.
