editing control.ini file on a LAN

I want to be able to change the screen saver settings section in the control.ini file on all workstations on my LAN. I would prefer not to have to manually change each and every machine. And each machine has a different control.ini file, so I needto be able to just modify the screensaver section. I would like to be able to change all machines at once. Any suggestions would be appreciated.

Thanks
