In a public computer lab, we want to set something up so that when a user starts to use the machine they have to accept terms of use that will appear on the screen by clicking an Accept button. We would also like this screen to show some graphics if possible.
When they are done using the computer it should revert back to this screen after the computer has been idle for 5 minutes. There are 3-4 machines at 17 different locations that are not on the same network. Setting all these machines up one at a time is acceptable.
These are all Windows machines, I think they are mostly XP, some may be newer.
Can someone recommend a program or any other way to do this easily?
