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.

Long Sent: Wednesday, December 28, 2005 3:09 PM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] Time Service 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?
