Thanks
I believe this is bascially what the other two were saying but since my brain isn't functioning properly today I didn't catch on. So instead of what I had previously I'd just use this:

Code:
$SERVERS = 'server1','server2','server3', 'etc'
FOR EACH $Computer In NetView2(@ldomain)
  IF $Computer 
	IF PING($Computer,0) AND AScan($Servers,$Computer)= -1
		SHUTDOWN ($Computer,"Your Computer is being shutdown to install an application", 45,  FORCE)
	ENDIF
  ENDIF
NEXT  

Exit


This should enumerate the domain using the NetView2, then if the computer Pings and is not in the array I create with my servers it should receive a shutdown command.
