Manually configure that DC?

Oh no, it's easier than that, it can be done with a Group Policy and a WMI 
query:

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.

I believe in a domain that the members get time from the PDC Emulator and the 
PDC Emulator talks out to the NTP Servers on the internet. 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.

it is, but now I'm questioning if the commas should be removed

Is the PDC virtual?  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?

Subject: [NTSysADM] time not syncing

Hi all,

i have follows these instructions to the letter, and have confirmed the values 
exist and are accurate in the registry of the 2008r2 DC, it remains 10 minutes 
off

All the computers, clients and servers, have the same time so its not causing 
any authentication issues (thankfully) but its annoying not be able to get the 
correct time

  1.  First, locate your PDC Server. Open the command prompt and type: 
C:\>netdom /query fsmo
  2.  Log in to your PDC Server and open the command prompt.
  3.  Stop the W32Time service: C:\>net stop w32time
  4.  Configure the external time sources, type: C:\> w32tm /config 
/syncfromflags:manual 
/manualpeerlist:"0.pool.ntp.org,1.pool.ntp.org,2.pool.ntp.org"
  5.  Make your PDC a reliable time source for the clients. Type: C:\>w32tm 
/config /reliable:yes
  6.  Start the w32time service: C:\>net start w32time
  7.  The 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].
Collecting 5 samples.
