  • Maybe you can use external NTP instead of local CMOS clock

  • Hi,

    Add some information, in order to change windows time settings we can use w32tm tool.

    Configure the Windows Time service on the PDC emulator in the Forest Root Domain

    Hope this helps.

  • Hello,

    without being member of the domain and syncing the time you may run into problems, depending on the needs of the machines in the DMZ.

    SO consider to open the firewalls for UDP port 123 so they can sync with the PDCEmulator or configure them to use the same time server as used from the PDCEmulator, that way you will have the option at least for the correct times.

  • Hello,


    The computer is member of a domain ? If yes, can you do a "w32tm /monitor" ?

  • not a part of domain

    these are workgroup machines in DMZ

  • Hi,

    Not sure which version of windows you are running, please try this:

    Error message when you run the "w32tm /resync" command to synchronize Windows Server 2003 or Windows SBS to an external time source: "The computer did not resync because no time data was available"

    http://support.microsoft.com/kb/929276

    Time synchronization is not performed even though the W32Time service is successfully started in Windows Server 2008 or in Windows Server 2008 R2

    http://support.microsoft.com/kb/2493006

    Hope this helps.
