Is there a way to put a Time on how long a wmi query to a remote box will stay in case a wmi is hang on a remote box, so it just go to the next box on the list.
I have encountered this a lot that a remote box is pingable but wmi is hang and the script will just sit there.

$erroractionpreference = "SilentlyContinue" does not work

also tried inserting winmgmt reset on script it helps but I still get stuck at times.

(get-service -comp $strComputer |where {$_.servicename -eq "winmgmt"}).stop()

I am thinking about putting a time limit when it queries a box once  it hit lets say 30 secs it will break up and move on to the next bxo on the list.

Thnx

You can put a timeout on the WMI query.
There is a timeout option in the wmi object, but you have to go through the psbase property.

Example:
$WMI = [wmi]''
$WMI.psbase.options.timeout = 20000000 #time in ticks - 2 seconds
$WMI.psbase.path = "\\computername\root\cimv2:Win32_Service.Name='BITS'"

After setting the path, when you access the variable $wmi, the query will be evaluated.

Ok.. after further testing and a note from Shay (http://blogs.microsoft.co.il/blogs/...natic/)... I found that the timeout property is specifically for enumerating a collection. So, depending on the kind of timeout that you are experiencing, this may or may not work.

There is another setting, $WMI.psbase.scope.options.timeout, that could affect the enumeration results.

You could also try using the [WMISearcher] accelerator. You can set the timeout option on that in several places. Additionally, there is a property under the Options property of the WMISearcher called ReturnImmediately. By default it should be set to true and should keep the query from hanging. I could not find the equivalent in the WMIClass accelerator.
One:
$searcher = [WMISearcher]
$searcher.options.timeout = '0:0:2' # 2 seconds, string is cast to a timespan object/alternative to using ticks

Two:
$searcher = [WMISearcher]
$searcher.scope.options.timeout = '0:0:2'

The fourth option is not PowerShell specific, but might help. On the target machine, run dcomcnfg.exe and navigate to the Component Services->My Computer. Right click and choose properties. On the options tab, there is a timeout (in seconds) for DCOM transactions. Fiddle with that at your own risk. :)
