Unable to view settings tab in one GPO. "An error occurred while generating report: Object reference not set to an instance of an object."

    Question

  • I am the owner of this GPO and I can view the settings tab in any other GPO. But, I get the following message when I try to view the settings tab in one particular GPO:

    An error occurred while generating report:
    Object reference not set to an instance of an object.

    Other posts I look at reference the same error, but with different circumstances, and thus, they specify that the hotfix is for to fix the error under those circumstances.

    I'm accessing GPMC on a Win 7 SP1 machine. DC is Server 2012 Standard.

    You can filter ADM templates to show configured ones only, and you can
    use the "show all settings" node. This will speed the work up - a little
    bit at least :)

    Most probable reason is a security setting W7 doesn't understand. Do you
    have a 8.1 workstation or 2012R2 server at hand?

  • I do have several OS's available, but none have the GPMC installed. I'll install it and try that.

    I was actually able to isolate the problem by making a copy of the GPO and removing items, one-by-one, from the unique ID folder for this GPO in the sysvol folder. Though, I still haven't been able to fix it, I found that when I remove the registry.pol file from the User folder, the error does not occur. However, when I do that, it removes the User side Administrative Templates tree that must contain the errant setting. Since I have to go through Edit to see the settings, and peruse the entire massive folder of settings to try to identify the bad one, it has been slow-going and I haven't found it yet. If you have any ideas, please let me know, thanks!
