Using remotecontrol.exe

I have a network of mostly version 5 MebX and am using the remotecontrol.exe utility to power the PCs on and off.  However, on one Dell model in particular (960) the powerdown command is the equivalent of pulling the plug, so the PC cannot re-cycle it's power as it does during a normal shutdown.  Therefore the NIC doesn't stay live so I can't send a powerup command.  Is there any way in vPro to send a Windows shutdown command instead of poweroff?  Thank you.
