  • Accidentally turned off DNS server service on a DC

    A junior administrator accidentally turned off the DNS server service on a DC, in an evironment where there are two DCs. The DNS server service on the other DC was running just fine.

    After about 4 hours, he noticed this and turned on the DNS server service on the DC, he had turned it off.

    The DC where he turned it off, holds all FSMO roles, and is configured as the primary DNS server on clients.

    I am thinking, there should be no issues due to this, as any changes in the DNS on DC number 2, where the DNS service was never turned off, will replicate to DNS on DC number 1, where the DNS service was turned off. As part of AD replicaton.

    Is my assumption correct? DC Number 1 has not been restarted since this occured.

    You are correct - same as server being down for patching - changes should replicate as soon as communication is restored

    But do something nasty to your junior admin (or at least make them sweat for a while )
