Check for WMI

[ChrisL]

A quick question, what is the best way to check if WMI is available in a script?

What would happen if you ran script which tried to querry some WMI stuff but WMI didn't exist?

$strComputer = 'localhost'
$objWMIService = ObjGet("winmgmts:\\" & $strComputer & "\root\CIMV2")
If @error Then
    MsgBox(0,"Error", "Couldn't connect to WMI")
    Exit
EndIf

$strComputer = 'localhost'
$objWMIService = ObjGet("winmgmts:\\" & $strComputer & "\root\CIMV2")
If @error Then
    MsgBox(0,"Error", "Couldn't connect to WMI")
    Exit
EndIf

Thanks

Is there anyway to make the check give up quicker if a machine is slow to respond or not going to respond? For some machines I run this on, it takes ~30 seconds to time out. If not, could a timer be implemented somehow to cancel the call if no response if received?

TimerInit()
TimerDiff()

P.S.

In the future time create your own topic.
