I have Domain Controller Windows 2012 R2, Recently I wanted to configure the following policy

Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> "Network access: Restrict clients allowed to make remote calls to SAM"

The Microsoft Learn say I need to install KB4012219

When I try to install this it says the update is not applicable on my computer

I have the prereqs installed

Anyone know what the issue is?

    Hello @LabDays

    KB4012219 released on 2017 is for the older version system, and your server has already update to the newest one, so that kb is no applied for your new version now.

    If you have questions about Setting up a Microsoft Defender, better open a new thread with related tag. More dedicated experts will be assigned to it.
