WMI Timeout with .NET question

Does anyone have an example of using .NET classes to issue a remote WMI call
with a timeout value specified? The cmdlet will hang in certain
circumstances indefinitely... which bites if you are 5 into a list of 100
computers I haven't discovered a way to programatically
monitor/trap/break out of a hung WMI, so I'm hoping using the .NET class
will allow me to circumvent this problem.

I should have added, that it's not a firewall type issue causing the
hang --- as it's only certain WMI calls. For instance... to the SAME
computer, I can do a

gwmi -co $cn -list
and even a
gwmi -co $cn -class win32_computersystem

but if I do a

gwmi -co $cn -class win32_service -filter "NAME like 'Symantec%AntiVirus'"

it hangs indefinitely (well I killed it at the 2 hour mark... I figured it
was safe to give up).

So in the long run, my ultimate goal is to allow the script to continue and
not have this 'hang' compromise the entire script's ability to complete.

you can give the timeout in the options in ticks (before setting class and
computer):

e.g. to make it 1,5 seconds :

$wmi = [wmi]''
PS H:\> $wmi.psbase.Options.timeout = 15000000
PS H:\> "$($wmi.psbase.Options.timeout)"
00:00:01.5000000

Using /\/\o\/\/'s example, I am able to set the timeout with below code:

PS ps:\> $wmi = [wmi]""
PS ps:\> $wmi.psbase.options.timeout = 15000000
PS ps:\> $wmi.path = "\\computer1\root\cimv2:Win32_Service.Name='Symantec
AntiVirus'"

but it does the same thing as get-wmiobject ... hangs. Grr! Part of this
scripts purpose is to find unhappy machines... but the ones that are most
unhappy are stopping the script cold.

Oh well... if anyone has any other ideas on how a script can recognize and
recover from these hangs, I'm all ears.

if its only on a couple of machines try deleting the repository directory.
could be WMI is corrupted
(you can test this first in computer management on the affected computer
(Service and applications -> WMI control properties))
if this not works WMI is corrupt, delete the repository directory

h.t.h.

Hi there!

I have the same problem with some of the machines I'm trying to connect to.
Now I think I finally found a way to set a timeout!
Here is what I did:

PS H:\> $options.set_Username("user")
PS H:\> $options.set_Password("password")
PS H:\> $timeout = new-timespan -seconds 5
PS H:\> $options.set_timeout($timeout) # this didn't help with the wmi
queries at all....
PS H:\> $Scope = new-object System.Management.ManagementScope
"\\someserver\root\cimv2", $options
PS H:\> $Scope.Connect()
PS H:\>
PS H:\> $query = new-object System.Management.ObjectQuery "SELECT * FROM
Win32_OperatingSystem"
PS H:\> $searcher = new-object System.Management.ManagementObjectSearcher
$scope,$query
PS H:\>
PS H:\> $SearchOption = $searcher.get_options()
##
$SearchOption returns something like this:

ReturnImmediately : True
BlockSize : 1
Rewindable : True
UseAmendedQualifiers : False
EnsureLocatable : False
PrototypeOnly : False
DirectRead : False
EnumerateDeep : False
Context : {}
Timeout : 10675199.02:48:05.4775807


PS H:\> $SearchOption.set_timeout($timeout)
## set new timeout
after setting the timeout:

ReturnImmediately : True
BlockSize : 1
Rewindable : True
UseAmendedQualifiers : False
EnsureLocatable : False
PrototypeOnly : False
DirectRead : False
EnumerateDeep : False
Context : {}
Timeout : 00:00:05

PS H:\> $searcher.set_options($SearchOption)
PS H:\>
PS H:\> $searcher.get()
An error occurred while enumerating through a collection: Timed out .
At line:1 char:14
+ $searcher.get( <<<< )
PS H:\>

->

Hope this helps. If someone refines the code please post it
