Automatic Remote Shutdown of W2K Servers

Powerchute has a command option for event actions. I want to use this to shut down several nonessential servers as soon as power becomes unavailable. We have more servers than UPS’, so I need to be able to do some of them automatically and remotely. The shutdown command that comes with the reskit won’t work if it’s run from a batch file; It doesn’t have appropriate permissions. Using runas doesn’t work because I still have to manually enter a password(redirecting it from a text file won’t work either) Any help would be greatly appreciated…
