We did that kind of system for a computer lab. Master node used cron to
reboot all the computers using rsh. All we needed was to setup rsh-daemon
for WinNT and use small utility for Partition Magic to change active
partition and to boot the computer. Linux side is much easier with lilo
and reboot.

Hope this helps.
