SCCM Powershell Script Fails Occasionally - Looking for guidance


  • I have the following script that we have been running for a number of months to create a consolidated updatelist from several individual update lists. 

    Suddenly beginning in 2012 we started getting the following errors.  This it may have to do with the size of the update lists.  It works sometime with only three months, but not four.  When using three months, sometimes it takes three times to run, but does run. (Why does it take three times)

    Any assistance on what is causing the issues.

    Conjecture is that it is either a timeout or a size issue.


    The following error does not seem too important as  the new consolidated update list is still created when only seeing this error.

    Cannot convert value "\\HSCUSCHLWS00079\root\sms\site_HCC:SMS_AuthorizationList
    .CI_ID=55004" to type "System.Management.ManagementObject". Error: "Not found "
    At C:\powershellscript\consolidated_updatelist.ps1:38 char:24
    +     $UpdateList = [wmi] <<<< "$($UpdateList.__PATH)"
        + CategoryInfo          : NotSpecified: (:) [], RuntimeException
        + FullyQualifiedErrorId : RuntimeException

    (Line 38 is the following: $UpdateList = [wmi]"$($UpdateList.__PATH)")

    This is the key error as the new consolidated update list is not created:

    (Line 99 is the following command:  $WmiAuthClassInst.Put())

    Exception calling "Put" with "0" argument(s): "Generic failure "
    At C:\powershellscript\consolidated_updatelist.ps1:99 char:22
    + $WmiAuthClassInst.Put <<<< ()
        + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
        + FullyQualifiedErrorId : DotNetMethodException

  • Surely someone must know how to assist.  The script only fails when there is a very large update list.

    It has to be some sort of timeout.
