Some computers are 5 to 6 minutes ahead in time RRS feed

  • Question

  • I have a DC acting as NTP internal Server but recently some users are complaining that their times are 5 to 6 minutes AHEAD of time.

    I followed the KB Article http://support.microsoft.com/kb/816042/en-us 3 years ago and works fine since then.

    Recently i have changed the PDC emulator to a new server and the old server was configured with the DOMHIER configuration to avoid 2 NTP Servers, reverting back to a "original" config, using a single NTP server.

    We installed a time-sensitive application and users are complaing about the 5-6 minutes wrong time.

    I created a Startup Script to every reboot, to force synch with the PDC emulator, using the net time /s /y command, but several minutes after, the time changes again to 5-6 minutes difference and stays ahead of time until a new net time /s /y command

    Some tip to me?

  • We discovered one VM/DC with "Time Synch" integration services enabled and the physical machine more thant 5 minutes ahead of time.

    Yesterday we changed the time in the HYper-V and we noticed tha most of the users have the LOGONSERVER variable pointed to this particular VM.

    We´re waiting the user feedback

    Just for make sure time will update, we´ll create a Startup Script to log and make certain that time will be updated at start time

    @echo off

    set TRANSFFOLDER=\\server\share\transf\
    set VERSION=1.5
    set TIMELOGFILE=%TEMPFOLDER%\ForceNetTimev_%VERSION%.LOG

    echo.

    echo ForceNetTime Version %VERSION%fb

    echo ForceNetTime
    NET TIME \\%TIMESERVER% /SET /YES > %TIMELOGFILE%
