i think i will be implementing the Meinberg to all sites thanks,
From: [email protected] To: [email protected] Date: Tue, 18 Feb 2014 08:50:22 -0500 Subject: RE: [NTSysADM] time not syncing Yes, member computers and non-PDC DCs in a domain sync to the PDC emulator for the domain. PDCs in child domains sync to the PDC emulator in the forest root domain. You should manually configure that DC to sync to an external source. This probably works great in modern times, but back in the server 2000 days, this was a bit brittle – the slightest disturbance in the force could cause time sync to go haywire. That’s why I installed the Meinberg NTP port on a couple of servers, configured them to talk to public NTP servers, and then configured all my PDC emulators to sync from them. This made for rock-solid time sync.

Way I remembered it a while ago when I did such things. Usually manually setting the list, is only done when systems aren’t part of domain. Z Edward E.

If it is, it could be pulling the time from the vm host. Is the vmhost set to the proper NTP server (”0.pool.ntp.org,1.pool.ntp.org,2.pool.ntp.org”) and not the PDC?

Open the command prompt and type: C:\>netdom /query fsmoLog in to your PDC Server and open the command prompt.Stop the W32Time service: C:\>net stop w32timeConfigure the external time sources, type: C:\> w32tm /config /syncfromflags:manual /manualpeerlist:”0.pool.ntp.org,1.pool.ntp.org,2.pool.ntp.org”Make your PDC a reliable time source for the clients. Type: C:\>w32tm /config /reliable:yesStart the w32time service: C:\>net start w32timeThe windows time service should begin synchronizing the time. You can check the external NTP servers in the time configuration by typing: C:\>w32tm /query /configuration when i run this command w32tm /stripchart /computer:0.pool.ntp.org /samples:5 /dataonly C:\>w32tm /stripchart /computer:0.pool.ntp.org /samples:5 /dataonly Tracking 0.pool.ntp.org [15.126.193.186:123].
