PS Script to monitor WinXP remote process...

Hi,

I'm looking for a way to run the execute the script below from a single host, via scheduled task to about 100 remote Win XP SP3 workstations.  I know I can reference a csv file in my script, but I'm not clear on how to inject that information in this particular case...

$programName = "wfica32"

$isRunning = (Get-Process | Where-Object { $_.Name -eq $programName }).Count -gt 0

if ($isRunning)
{ }
else
{ Start-Process C:\temp\down.cmd }

Any help would be appreciated!
