My sbs 2008 keeps reverting to free running system clock after being virtualized in preparation for migration to sbs 2011

    Question

  • I have read all the solutions in the forums, none seem to get me to be able to sync with external time source. I have unreg'd, rereg'd and set up from scratch. Time sync service in NOT on the Hyper V Host, so thats not the issue. When I run w32tm /query /status, this is what I get after a day or so

     

    Microsoft Windows [Version 6.0.6002]
    Copyright (c) 2006 Microsoft Corporation.  All rights reserved.

    C:\Windows\System32>w32tm /query /status
    Leap Indicator: 0(no warning)
    Stratum: 1 (primary reference - syncd by radio clock)
    Precision: -6 (15.625ms per tick)
    Root Delay: 0.0000000s
    Root Dispersion: 10.0000000s
    ReferenceId: 0x4C4F434C (source name:  "LOCL")
    Last Successful Sync Time: 06/05/2011 8:14:10 AM
    Source: Free-running System Clock
    Poll Interval: 6 (64s)

     

    When I reset the settings and start over, it will state cmos clock and the time will stay, but still no external sync. This only lasted a day or so, then back to free running clock wich drifts badly.

     

    Server has been rebooted and started the w32tm service etc, but the two issues are: will not sync to external source regardless of ntp chosen. I can run this:

    C:\Users\ITAdmin>w32tm /monitor /computers:time-b.timefreq.bldrdoc.gov
    time-b.timefreq.bldrdoc.gov[132.163.4.101:123]:
        ICMP: 52ms delay
        NTP: -4.0575485s offset from local clock
            RefID: 'ACTS' [0x53544341]
            Stratum: 1
     and verify its not a network issue, but still at a loss.Any suggestions woud be appreciated. Here is a break down of what I have done:

    C:\Users\ITAdmin>net stop w32time
    The Windows Time service is stopping.
    The Windows Time service was stopped successfully.

    C:\Users\ITAdmin>w32tm /config /manualpeerlist:time.windows.com,0x1 /syncfromfla
    gs:manual /reliable:yes /update
    The command completed successfully.

    C:\Users\ITAdmin>net start w32time
    The Windows Time service is starting.
    The Windows Time service was started successfully.

    C:\Users\ITAdmin>w32tm /query /status
    Leap Indicator: 0(no warning)
    Stratum: 1 (primary reference - syncd by radio clock)
    Precision: -6 (15.625ms per tick)
    Root Delay: 0.0000000s
    Root Dispersion: 10.0000000s
    ReferenceId: 0x4C4F434C (source name:  "LOCL")
    Last Successful Sync Time: 04/05/2011 9:49:40 AM
    Source: Local CMOS Clock
    Poll Interval: 6 (64s)

    I have skipped th paste of un reg andf reg, as I did not keep a log of that for pasting.

  • Any errors for the time service in the logs, like - unable to contact time server, reverting to free running clock, etc?

    Also i think a lot of people havre more success with pool.ntp.org as a source.

  • When I reconfigure to any "new" ntp server, all i get is a move from free running systen clock to cmos clock.

     

    Again, I cam manually do a monitor and see ntp works. Here is my check from this morning. Time was hours off, and this is what I performed:

  • it was a policy that was killing the setup. Previous admin set up policy at root and not just on clients.

     

    Thank you very much.

  • Would you mind telling me what policy was causing this and steps you took to remove it? I am having exactly the same issue except on server 2008 r2 :(

    Thank you so much it's been driving me mad

  • Have you been able to review the question from Gostega? I would love to know what policy was doing this to you...

  • if a policy is causing it, a gpresult should tell you what it is...

  • Can you post what policy setting that is causing this and steps you took to remove it? I could not find any GPO setting from GPresult for a time setting.

  • Under domain controllers' group policy, computer config\policies\administrative templates\system\windows time providers....make sure "enable windows ntp server" is enabled, I apologize, I'm recalling the path above from memory, so I might be a little off, but that is the main issue if your udp port is not blocked.
