  • 2008 R2 & NTP Clients.

    Dummy question.

    I have a 2008 R2 domain controller.

    Do I need to configure the ntp client on all clients using gp or do
    they automatically sync up with the DC ?

    Here is the config on the DC.

    Re: 2008 R2 & NTP Clients.

    I've never manually configured it on domain members - they should pick it up automatically from the domain.
