OK, so then I am still not synching with an external time source. I have followed the steps, and still I get the same thing. I can not figure out what it causing it to not use the server I specify. I am guessing it has something to do with some group policy setting? Do I need to block inheritance on the default domain controller GPO and have different settings?

To keep things simple, doing

 

Net time /setsntp:pool.ntp.org

 

then

 

net stop w32time& net start w32time

 

and

 

net time /querysntp

 

(ALL at the PDC-E) should give acceptable result. If it doesn’t, then something at the firewall may be blocking 123

I have Run w32tm /config /update /syncfromflags:MANUAL /manualpeerlist: “navobs1.oar.net” and also verified HKLM\System\CCS\Services\w32time\Parameters

Type=NTP is set. I stopped and started w32time, and still the PDC-E points to itself. Or at least that is what I think it is saying. Isn’t LOCL in the following telling me that it is looking at itself instead of an external time source?

 

 

w32tm /monitor

 

dc1.domain.com *** PDC *** [10.100.110.12]:

    ICMP: 0ms delay.

    NTP: +0.0000000s offset from dc1.domain.com

Hi Douglas,

 

To configure domain members and DCs to use the default behavior, either

 

Run w32tm /config /update /syncfromflags:DOMHIER

 

Or check the following registrykey

 

HKLM\System\CCS\Services\w32time\Parameters

Type=NT5DS

 

To configure a server to use a NTP-Timesource (what you want to do on the PDC-E of the forest root):

 

Run w32tm /config /update /syncfromflags:MANUAL /manualpeerlist:”fqdn1 fqdn2 ip1”

 

Or check the following registrykeys

HKLM\System\CCS\Services\w32time\Parameters

Type=NTP

NTPServer=”fqdn1 fqdn2 ip1”

 

To configure a server to trust his BIOS-Clock (test-environment) or which is getting it’s time from a 3rd party soft- or hardware attached locally check the following reg-keys:

 

HKLM\System\CCS\Services\w32time\Parameters

Type=NoSync

ReliableTimeSource = 1 (reg_dword)

 

 

Afterwards I’d restart w32time using

net stop w32time && net start w32time

 

Gruesse - Sincerely,

Ulf B. Simon-Weidner

I have read the Time Service white paper from Microsoft and am still confused. I have set the default domain GPO to use NT5DS under Configure Windows NTP Client, and set an external time server (navobs1.oar.net,0x1) for NTPServer. I have also set Enable Windows NTP Server to enabled. There are no other time related GPOs set in the domain. I was under the assumption that with that setting my PDC emulator (DC1) should be synching with navobs1.oar.net,0x1 and the other DC synchs with the PDC emulator, and then all clients synch to the closest DC. When I run a w32tm /monitor from the either DC or from any clients, I get the following.

 

dc1.domain.com *** PDC *** [10.100.110.12]:

    ICMP: 0ms delay.

    NTP: +0.0000000s offset from dc1.domain.com

        RefID: 'LOCL' [76.79.67.76]

dc2.domain.com [10.100.110.13]:

    ICMP: 0ms delay.

    NTP: +0.0226641s offset from dc1.domain.com

        RefID: dc1.domain.com [10.100.110.12]

 

When I run it from a client:

 

dc1.domain.com *** PDC *** [10.100.110.12]:

    ICMP: 0ms delay.

    NTP: +0.0000000s offset from dc1.domain.com

        RefID: 'LOCL' [76.79.67.76]

dc2.domain.com [10.100.110.13]:

    ICMP: 8ms delay.

    NTP: +0.0342476s offset from dc1.domain.com

        RefID: dc1.domain.com [10.100.110.12]

 

What I am seeing is that everything is working except DC1 is not synching with an external time server. Is that correct, or am I reading that wrong? If it isn’t synching with an external time source, what setting am I missing?
