A custom attribute was mistakenly created in Windows Core Library MP. This attribute is causing WMI errors on all of my servers. How can I remove the attribute from Windows Core LIbrary?

    So, the discovery causing your issue is called "Group - SEC_SRVADMIN_SERVER_SUPPORTDiscovery" and is stored in the Management Pack called "AD.Partner.Management.Pack"
    (try Get-SCOMManagementPack -Name "AD.Partner.Management.Pack" to find its displayname)

    If I were you, I would export that MP and check in the XML code what that discovery does precisely before savagely deleting it.

    Hi,

    Just to confirm with you, can we locate the customized attribute by searching from operations manager console?

    Can you explain your issue with a bit more details? I don't believe you could have created a custom attribute in the Windows Core LIbrary Management Pack, since it is a sealed MP...

    HI @Keith Langley ,

    you can't do this. As Cyril stated this library is actually sealed and cannot be modified.
    I doubt that you have been able to extend a class in this library with a new attribute, so it would be interssting to find out what exactly happened.
    Can you eventually post here more details so we can try and help you?

    Regards,
    Stoyan

    The attribute was created on 10/23 using instructions from a website that I can no longer find

    I deleted the management pack I thought I had created the process in and thought I had gotten rid of it.

    This is the alert still occurring on all my servers

    ------------------------------------------------------------------------

    Object enumeration failed

    Query: 'select * from Win32_OperatingSystem where (ProductType = "2"'

    -------------------------------------------------------------------------

    In searching for a cause I found attributes with a 10/23/20 created date in Windows Core Library.
