You can set Windows 7 to have a screensaver that is just a slideshow of pictures tossed in a certain directory.  Likely the easiest approach is to make all those service ads into images, stick them in a directory on each machine and then tweak your machine to use that directory for its screensaver and keep the monitor on for the desired amount of time via power settings.

You can also use that same directory to show custom desktop backgrounds that change ever X minutes and pop the ads up there.

Subject: [CODE4LIB] Windows 7 Logon Screen Screensaver

This is a long shot, I believe, but members of this group have answers.

On our Windows XP Pro student use computers, we have a custom screensaver app that runs at the logon screen and displays graphics highlighting library services and programs.   As we migrate to Windows 7, new security introduced by Microsoft limits access to custom applications when the logon screen is displayed, and we haven't figured out how to push the screensaver to the machine.   For obvious reasons we need to move to Windows 7.

Does anyone have a solution that pushes a custom screensaver to the Windows 7 logon screen?   Thanks.
