Isn't it best practice to set the entire domain time policy at the domain level (Default Domain Policy) instead of trying to set every machine or every OU separately?

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? _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, December 28, 2005 12:03 PM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] Time Service 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.

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?
