HI All,

I have applied new KB4580346 but it did not resolve the problem. Error "MMC has detected an error in a snap-in” still appearing.

Deleting the regkey HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SecEdit\Reg Values\MACHINE/Software/Microsoft/Windows/CurrentVersion/Policies/System/DontDisplayLockedUserId does not helps either.

Any help is greatly appreciated.

Windows Server 2016
Windows Server 2016
A Microsoft server operating system that supports enterprise-level management updated to data storage.

    Hello @ShannLim-3692,

    Thank you for posting here.

    1.What is the operating system of this server?

    2.Do you mean you installed 2020-09 Cumulative Update (KB4577015) on this machine? If so, it will affect Windows 10 1607 and Windows 2016.

    If we installed 2020-09 Cumulative Update (KB4577015), the security options of the local group policy cannot be opened, and the error is reported as follows:

    Now there is solution to this problem. Please install the following patches KB4580346 on the problematic servers (OS Build 14393.3986).
    Based on your description above, you have installed this update, please run PS command get-hotfix on this problematic server, then check if we installed KB4580346 actually.

    For example:

    If we did not install KB4580346, please install it to see if it helps.

    If we have installed KB4580346, please restart this problematic machine to see if it helps.

    Hello @MS Lee ,

    We can uninstall KB4577015 and KB4580346, then install KB4577015 firstly, then install KB4580346 secondly to see if it helps.

    Best Regards,
    Daisy Zhou

    Hello @Cheng Siyuan ,

    Is your server a DC or a member server or a server in workgroup?

    We can uninstall KB4580346, then install KB4577015 firstly, then install KB4580346 secondly to see if it helps.

    If it does not work and it is a DC, we can remove "Group Policy Management" and add "Group Policy Management" again to see if it helps.

    Best Regards,
    Daisy Zhou
