SNTP Setup on Windows 2003

Discussion in 'Server Setup' started by Anthony Lopez, Jul 29, 2009.

  1. I am attempting to sync our new Windows 2003 Standard Edition R2 server to
    our network NTP time source device. I have done this for our other Windows
    2000 servers with out a problem.

    I have made similar changes to the W2k3 server to no good avail. Why did it
    get so much more difficult?

  2. Hello Anthony,

    Is that a workgroup server or domain controller?

    Best regards

  5. Hello Anthony,

    Be sure that UDP/123 is open when a firewall is used. Run following command:

    w32tm /config /manualpeerlist:pEERS /syncfromflags:manual /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/


    Best regards

  6. We have a LAN device which is our Stratum-1 time source for all host. It
    provides NTP and SNTP version 1, 2, and 3 frames.

    Made your suggested changes as described below

    Ensured that Firewall is turned off

    Just turned off Group Policy

    Did a: Stop/Start of w32time

    Did a: w32tm /resync /rediscover and got the following error response:
    "The computer did not resync because no time data was available."

  7. Hello Anthony,

    Please post the command you used. Also what did you mean with turned off
    Group policy? Do you use GPOs for time configuration?

    Best regards

  8. Here are the commands that I used

    Gpedit.msc

    Local Computer Policy | Computer Configuration | Administrative
    Configuration | System | Windows Time Service | Time Providers | Configure
    Windows NTP Client = Not Configured

    Gpupdate /force

    Net stop w32time && Net start w32time

    w32tm /resync /rediscover

  9. Hello Anthony,

    So you didn't use:
    w32tm /config /manualpeerlist:pEERS /syncfromflags:manual /update

    where PEERS is replaced with ip address from your stratum device?

    Best regards

  10. I sort of thought you were asking about the additional commands I used.
    Below is the revised edition


    w32tm /config /manualpeerlist:pEERS /syncfromflags:manual /update

  14. Hello Anthony,

    Do you have any policy setting according to the time service configured?
    In a command prompt type:
    rsop

    and control the output.

    Best regards

  15. Well at a command prompt

    RSOP
    and
    RSOP.EXE

    Did not work.

    So I tried RSOP.MSC and that brought up the "Resultant Set of Policy" dialog
    box. I did not see anything dealing with time other than "Windows Time" for
    which neither Startup or Permission had anything defined.

  16. RSOP did not work.

    RSOP.MSC did work and no policy set for windows time.

    Is there something else we can try?

  17. OK back from Vacation. Is there anything else we can try?

    Recap: I am trying to get Windows 2003 Server to sync up with an external
    NTP/SNTP network device, which is connected to our LAN

  18. If the aforementioned attempts fail, are we giving up. Can Windows 2003
    server connect to an external NTP/SNTP device or not?

  19. Hello Anthony,

    It can as described before. Why it doesn' t work in your case, when you follow
    all described ways i can't see.

    Best regards
