Good Day all, Just wondering if anybody has an idea on how I can change the screen resolution on about 750 Windows 2000/XP machines?

I've got an app that currently runs at 800x600 but a newer version is coming out that runs at 1024x768 and I need to change the screen resolutions (hopefully remotely).

We are running NW 6.5 with Zen 7.

Any input would be greatly appreciated.
