  • DC will not communicate with autoritative time server

    DC1 Autoritative time server (FSMO) GC
    DC1 configured to use mutiple sources
    (172.16.0.1 ntp-1.mcs.anl.gov ntp-2.mcs.anl.gov now.cis.okstate.edu ns.nts.umn.edu ntp-0.cso.uiuc.edu)?


    DC2 Exchange server
    DC2 mutiple event 29, event 14 trying to reach DC1 (NTP server)

    I have used the net time /set- no luck

    Set DC2 as secondary

    net time /querysntp
    The current SNTP value is: 172.16.0.1,0x2 140.221.9.20,0x2 ntp-2.mcs.anl.gov,0x2
    now.cis.okstate.edu,0x2 ns.nts.umn.edu,0x2 ntp-0.cso.uiuc.edu,0x2

    The command completed successfully.

    Still gets event errors 14 and 29


    Question

    How do I force DC2 to accept DC1 as authoritative time source?

    Just a little more info

    Reconfigured the authoratative DC (DC1)

    Ran on DC2
    w32tm /resync /rediscover
    Sending resync command to local computer...
    The computer did not resync because no time data was available.

    However- If I run this on other domain computers it is successful

      Hi,

      Share what are the entries under following registry key:

      HKLM\CCS\Services\W32Time\Parameters

      Share it from both DC and Exchange.

          Hi,

          In the type change it to "NT5DS" without quotes. NTP was being used in older versions.

          Cahnge it "NT5DS" for both ADC as well as Exchange. It will do......
