Windows Time Service EventID 50 RRS feed

  • Question

  • Dear All,

    I have running Exchange Server 2010 SP1 with windows Server 2008 R2.

    I getting the error log:

    The time service detected a time difference of greater than 5000 milliseconds  for 900 seconds. The time difference might be caused by synchronization with  low-accuracy time sources or by suboptimal network conditions. The time service is no longer synchronized and cannot provide the time to other clients or update  the system clock. When a valid time stamp is received from a time service  provider, the time service will correct itself.

    Do you have any idear and solution?

    BR,

  • Hello,

    make sure that no firewall blocks port 123 udp so it can connect to an available DC for time sync. Please run the following command on the server to resync:

    w32tm /config /syncfromflags:domhier /update

    After that you have to run:
    net stop w32time
    net start w32time

  • Hello,

    you a time sync problem.

    Please make sure that each server / client computer is using the PDC Emulator for time sync and that this DC is available.

    Also, make sure that the PDC Emulator is syncing time with a public NTP server.

    Refer to that: http://social.technet.microsoft.com/Forums/en/winservergen/thread/1946eb1b-e677-456c-86aa-0308a8cb834f

  • try in elevated command prompt:

    w32tm /resync /rediscover

    additionally doulbe check that your server has proper time source [generally it should be DC with PDC role] also check that there are no network issues to sync time from that DC (port 123 closed on firewall for example)


    With kind regards

  • Hi,

    Usually the domain controller that holds the PDC emulator role holds also the time setting for the whole domain. If you want to make some adjustments check this,

    Try configuring a different time source. For a list of time servers available on the internet go to http://support.microsoft.com/kb/262680.

     

    Good luck.
