How to Reboot machine at a scheduled time?

We have the same problem, users that never boot their computer, never want a delay, never give time to perform maintenance. We force the Windows update every Wednesday night and then use Desktop Authority to run a batch file at 1am which calls "shutdown /r" and forcibly reboots the PC's. This has been very successful....

EXCEPT.

I don't know what is up with Desktop Authority scheduler, but even when the rule is scheduled to run at 1am and not run later, sometimes it pops up in the middle of the day. So we added in some logic in the batch file to track with log files what is happening and try to prevent it from running after 3am but also so that if it does pop up the user has a chance to abort it. The batch file we run is:

SET Hour=%Time:~0,2%
if %Hour% LEQ 3 (
  echo shutdown attempted at %TIME% %DATE% >>c:\shutdownlog.log
  Shutdown /r /t 600 /c "Your computer is being restarted by the tech department for weekly maintenance. To cancel shutdown press any key."
  echo Your computer will reboot in 10 minute press any key to cancel.
  pause
  SHUTDOWN /A
) else (
  echo Shutdown of %COMPUTERNAME% attempted at %DATE% at %TIME%, outside of window...aborted >>\\tech\c$\ShutdownFailedLog.log
)
Exit
