In the previous tip we illustrated how WMI can ping computers with a predefined timeout. WMI can do more: it can ping multiple computers lightning fast even though the syntax is a bit awkward.
Here is how you can ping more than one computer:
# ping the specified servers with a given timeout (milliseconds)
$TimeoutMillisec = 1000
Get-WmiObject -Class Win32_PingStatus -Filter "(Address='microsoft.com' or Address='r13-c14' or Address='google.com') and timeout=$TimeoutMillisec" | Select-Object -Property Address, StatusCode
