    MS-DEFCON 1

    By Susan Bradley

    For those running a network with a domain controller, the side effects this month are extreme. Don’t patch.

    MS-DEFCON 1 is a very rare occurrence. When I raise the level that high, it’s because I’m seeing critical issues with patches.

    Microsoft has a technology called Active Directory that allows workstations to authenticate with a “domain controller.” This month’s updates are causing such drastic issues with domain controllers that they can become stuck in a boot loop. That is definitely an MS-DEFCON 1 condition. You should not release patches.
