Hello everyone,
In my domain I'm trying to sync my PDC emulator to a VM which I installed meinberg NTP on. The commands I used are:
w32tm.exe /config /syncfromflags:manual /manualpeerlist:192.168.50.108,0x8 /reliable:yes /update
and
w32tm.exe /config /update
Despite this the PDC emulator won't sync.
When I run the command: w32tm resync I get "The computer did not resync because no time data was available."
When I run the command: w32tm /query /source I still get local CMOS clock.
When I run the the same commands on the a workstation in the domain it will sync without problems. The other DC the non pdc emulator won't sync aswell.
The firewall allows port 123 in both directions and I tried turning the firewall off (lab enviroment).
I altered the default DC GPO: Time Providers -> Windows NTP client and Windows NTP server enabled.
I added the registry entries aswell.
Does anybody have an idea why my domain controllers won't sync but other workstations will?
Thanks in advance
Regards Daniël

Was there an answer to this for NON multihomed DCs? Having the same issue on Server 2022 version now

Please start a new thread.
The PDCe is multi-homed which will always cause no end to grief for active directory. This is also the root cause for the time sync problems.

Might try
W32TM /stripchart /computer:192.168.50.108 /samples:5
Then also drop the 0x8 as in
w32tm /unregister
net stop w32time
w32tm /register
net start w32time
w32tm /config /manualpeerlist:192.168.50.108 /syncfromflags:manual /reliable:yes /update
net stop w32time
net start w32time
then check
w32tm /query /source
w32tm /query /configuration

Hello Patrick, thanks for your response. I tried your answer, I do get result with the W32TM /stripchart. But for some reason my DC still won't sync. I added the results.
Regards Daniël
Btw, The stripchart won't work while using the 0x8 parameter*
Windows time service could not be stopped
May need to reboot
I'd check that the PDCe is not using host for time source via integration services.
Also an unedited ipconfig /all of time source and PDCe may help.
Reboot did not work.
I'm using VMWare not Hyper V. The timesync feature is disabled.
I added the ipconfig /all of the PDCe and the Time Source.
Yes, that's correct. The domain controllers should be all on their own instance of windows without other roles.

Okey, well I'm going to try that! I'll make sure to let you know if it works and I'll mark your answer as such when it does. Thanks for all your help!
Sounds good, you're welcome.
Okey I added another DC linked it with the time source without problems. I made that DC the PCDe and I ran the command w32tm /config /syncfromflags:domhier /update on the other DC. How do I know the other DC's sync with the PCDe? When I run the command w32tm /query /source it will still say local cmos clock.
Btw SRV1 is the PDCe and DESKTOP-3U**** is the time source.
