  • Time Sync Issues


    I would like to set the clock on all my pc's within the domain to the same upon logging on each morning, is there something I can do to make this happen? Currently, Im having to manually adjust them every now and then but there must be a better way than that?

    Hope you guys can help.

    All domain members should sync their time with the DC that's holding the FSMO - PDC Emulator. Check out the following article for more info:

      In an active directory environment you dont have to sync time each morning with a script. Just configure the right W32Time service parameters in hKey_Local_Machine will make the client sync time from a domain controller by it self.

      You can configure this with a GPO for the client computers:
      Computer configuration/Administrative Templates/System/Windows Time Service/Time Providers --->
      Enable Windows NTP client =enabled
      Configure NTP client =enabled
      -> Type: NT5DS
      -> other parameters: 2 / 15 / 7 / 3600 / 0
      Enable NTP Server =disabled

      By default, only the Domain Controller that is holding the rol of PDC-emulator is the authoritative time server in the domain hierarchy.
      - Local Domain Controllers only synchronizes with a reliable time source, it does not attempt to synchronize with itself
      - By default a PDC emulator tries to synchronize with a reliable time server on the internet (but that can also be any domain controller in the parent domain)
      - All other DCs by default sync with the PDC emulator.
      - All member servers and all clients sync with a DC.
      That way you can be sure every computer in the domain has at leased the same time (wether that is the correct time or wrong time).

        OR, add the 004 into the DHCP Scope Option (assuming one is using DHCP to assign IPs on your network).
        1 1 was a racehorse.
        2 2 was 1 2.
        1 1 1 1 race 1 day,
        2 2 1 1 2
