target restart on certian computers.

Hello

I have 5 mac pro towers that i have to restart daily, at the moment I have been using a blanket "system events restart" apple script that is sent to each computer and it reboots all computers at the same time.

I now need to target each mac pro, perhaps via IP address, to have it reboot individually. i have been trying to use the script:

tell application "System Events" of machine "eppc://sedna:presenter@10.123.43.45"

to restart

but I keep getting a message back saying that the applicaiton is not running.

Maybe I need to do this with a unix (shell) script, similar to how ARD would send a reboot command to a partiuclar computer in my list.
