NTP settings on Windows 2008 reverting to Local CMOS Clock
I have set multiple domain servers in multiple domains to point to an external source for thier time. All have functioned properly except one. When I w32tm /query /source I get Local CMOS clock.
To configure the time settings I type the command:
w32tm /config /manualpeerlist:<IPADDRESS > /syncfromflags:manual /update
I have stopped and started service, unregistered and reregistered w32tm dll.
Sometimes this gets it to work temporarily, but it always reverts back and many times I can't make the change.
In the registry, under w32time/Parameters key, the "NTPServer" value is set to the proper IPADDRESS above, the "Type" value is set to NTP.
All settings match other DCs that function properly except under NTPServer Key. Here it is missing the all the values that start with "Chain". I added them manually and they soon disapear. I'm not sure how important this is to getting the source setup.
Thanks in advance for help

The only DC you need to point at an external time source is the one with the PDC Emulator FSMO role. All of the other DCs, along with every other machine in the domain, can be configured to simply get their time from the domain hierarchy. It can still work with every DC using an external time source, as long as they're all able to reach it regularly, but that's making things more complicated than they need to be.
thats the beauty of the WMI filter it move the authoritative time source to which ever is running the PDCe Role. Any other domain controller is configured to take domain time.
you can use the other DC's to push out NTP but its not needed

Today the value 10 persisted, but source did not. I changed back to 5 and now it works. I'm confused what about my process is making it work and what I need to set to make it stay working.
