I currently run the batch script:
start c:\psshutdown.exe -s -t 03 -f @ws.txt
WS.txt is simply a list of every computer name of the 140 odd workstations in this site. Now, I have tested this out and it works fantastic, but the problem is it takes up to an hour just to shutdown a 20 workstation computer lab. All workstations are WinXP SP2.
Is there a way to make psshutdown work faster instead of taking 2-3mins to timeout if it can't find if a machine?
