ScreenSaver not initializing!

I am having some problems with the SCR files I have created. I am referencing the screensaver form a network location. It works fine on Win95, 2000, and XP machines. However, it will not work on NT 4 Workstations. I go in and check the screen saver properties, and the screensaver is selected and you can preview it. It just will not automatically start itself. If I put a copy of the screensaver locally, it works just fine. Can someone give me some direction? Thanks for any help!
