I'm sorry, your right. I liked the program so much I forgot you were looking for logoff, not remote restart. You can have your cookie back :-(

From the README
You can use poweroff to do a reboot/shutdown on a remote NT/2000 system
(logoff and poweroff are not supported by windows )

Oh well, sorry about that. Still a nice program for those of us who want these other features.
