Check DC time

    We have a domain with around 120 DCs across various parts of the world,
    and it appears there is at least on rogue DC with incorrect time
    settings. Is there any tool available to check the time on all the DCs
    and report back any anomalies?

  2. How does "it appear"? If you know it is happening then why don't you know
    what DC it is? By the same token, if you don't know what DC it is, then how
    to you know it is even happening?

    A client computer set to the correct time on a subnet not defined in
    sites and services (ie it will randomly select a DC for authentication)
    will refuse to log on due to a time difference with the DC.

    Manually checking every DC is not a realistic option.

  4. There should not be any subnets "not defined" in Sites & Services.

    Assign all the "unassigned" Subnets to a correct Site.

    Wait to see what machine has problems after that,...the DC in the same site
    will be the one with the time problem. If there is more than one DC in the
    Site,...and one has a PDC role,...then that is the DC. If there are
    multiple DCs in the Site, and none have the PDC role,...then at least you
    narrowed it down to the smaller number of DCs in the one Site.

    It occurs to me that this shouldn't be substantially difficult to script
    since the time is remotely queryable.
