    Configuring Windows Time Service on windows Server 2003

    I would like to configure the Windows Time Service on our PDC emulator to
    synchronise with an external time source. After my initial investigation, I
    understand that you can either edit the registry as per KB816042 or use the
    w32tm command.
    Does it matter which option I select?
    Can I use Group Policy to alter the Windows Time Service on the PDC emulator?
    Is the w32tm command a one of synchronization or will it regularly
    synchronize?
    Your guidance is appreciated.
    Regards

    Hello lmg,

    I would not work in the registry, easier with one command line on the PDCEmulator.

    w32tm /config /manualpeerlist:peers /syncfromflags:manual /reliable:yes /update

    With "peers" you can set the time source, either DNS name (time.windows.com)
    or an ip address from a reliable time source.

    Here you can find some of them:
    http://www.pool.ntp.org/


    GPO you can use for the clients setup, but i would let them work as default.
    Default in a domain means, all DC's sync with the PDCEmulator and all member
    servers and workstations sync with one of the available DC's, doesn't matter
    which one.

    Time sync occurs after every reboot and regulary.

    Best regards

    Dear Customer,

    Thank you for posting in newsgroup. And thanks to Meinolf for the
    contributions.

    According to the description, you want to configure the Windows Time
    Service on our PDC emulator to synchronize with an external time source. If
    I have any misunderstanding, please feel free to let me know.

    Based on the research, here is some information which may be helpful for
    you.

    Analysis and Suggestions:
    =====================

    1. You may refer to Microsoft Knowledge base KB 816042 to configure an
    authoritative time server in Windows Server 2003:

    http://support.microsoft.com/kb/816042

    You may also run the w32tm command-line on the PEC emulator operation
    master to configure with synchronizing with the external time server
    regularly.

    Ex. w32tm /config /manualpeerlist:peers /syncfromflags:manual /reliable:yes
    /update

    /manualpeerlist:peers
    Set the manual peer list to <peers>, which is a space-delimited list of DNS
    or IP address of the reliable external time server.

    /syncfromflags:manual
    Set what sources the NTP client should sync from.

    /reliable:yes
    Set this machine is a reliable time server

    /update:
    Set the time service configuration update.

    Since the PDC emulator operations master at the root of the forest becomes
    authoritative for the organization. We would like to suggest that you
    configure the authoritative time server to gather the time from a reliable
    external hardware source. We also recommend that you reduce your time
    correction settings for your servers and stand-alone clients. These
    recommendations provide more accuracy and security to your domain.

    2. For your concern about using Group Policy to alter the Windows Time
    Service on the PDC emulator, the authoritative Windows Time server cannot
    be changed with GPO on PDC emulator. However, you may use Group Policy to
    make all the domain clients to sync time with the authoritative time server
    in the domain.

    You can find the Group Policy settings used to configure W32Time in the
    Group Policy Object Editor snap-in in the following locations:

    Configure Global Configuration Settings here.
    Computer Configuration\Administrative Templates\System\Windows Time Service

    Configure Windows NTP Client settings here.
    Computer Configuration\Administrative Templates\System\Windows Time
    Service\Time Providers

    3. Is w32tm command a one of synchronization or will it regularly
    synchronize?

    Yes, You may use following example to sync the time server every time the
    server is reboot.

    Ex. w32tm /config /manualpeerlist:peers /syncfromflags:manual /reliable:yes
    /update

    Generally speaking, after you configure time server, Windows Time service
    will synchronize time periodically.
