W32Time not synchronizing with PDC after /syncfromflags:domhier
We have two domain controllers on a local network:
Zeus [PDC]
Neptune
Zeus is configured to pull from an external time source and is set as reliable:
w32tm /config /manualpeerlist:0.pool.ntp.org /syncfromflags:manual /reliable:yes /update
However, when setting Neptune to pull from the domain hierarchy, or, even configuring to pull from Zeus directly, W32Time always just pulls from CMOS:
w32tm /config /syncfromflags:domhier /update
Source: Local CMOS Clock
w32tm /config /manualpeerlist:zeus.example.com /syncfromflags:manual /update
Source: Local CMOS Clock
I've tried unregistering and reregistering Windows Time on Neptune to no avail:
net stop w32time
w32tm /unregister
w32tm /register
net start w32time
Zeus' firewall allows all incoming traffic on domain networks for purposes of testing, and there's no other network devices in between them.

Late response I know, but a few comments/observations from someone who has wrestled with this. Note: I don't claim to know the answer directly to your question.
- Have you submitted a resync after these config changes?
- What do your Event Logs say? Windows-Time can be quite vocal and gives reasonably good troubleshooting guidance.
- I wouldn't use the NTP pool for time sync with Windows domains. I previously read that Windows isn't fond of the change in servers stratums which is commonplace between requests.
- On your second DC why not just set it to also sync from a manual peer list and see if that alters things.
- Extension of 3, here you can find a list of servers to sync with. You should even be able to find some stratum 1 servers in your region. I'm in the UK and have maintained perfect time sync using
ntppub.le.ac.uk,ntp.cis.strath.ac.ukandntp2c.mcc.ac.ukfor years.
A previous question of mine generated a great response and there's tons of info here on this subject.
