Hi everyone, I hope I'm right here with this question and you can help me with an issue that follows me since a few months now where I'm struggling with the NTP synchronization on my windows 10 PC...
The issue only happens with this one device, all other devices can sync their time with whichever ntp server I chose.
I'm even able to contact the ntp server via netcat on this exact device (Opensuse running via WSL), so it's definitely not a network issue:
nc -u -vvv time.windows.com 123
Connection to time.windows.com 123 port [udp/ntp] succeeded!
I tried all the standard solutions:
- stop and restart the
Windows Timeservice - change ntp pool
- unregister and re-register via cmd:
net stop w32time
w32tm /unregister
w32tm /register
net start w32time
w32tm /resync
Sending resync command to local computer
The computer did not resync because no time data was available.
- the peers seem to be listed correctly if I query them:
w32tm /query /peers

- Defining the servers in the registry
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers - Also,
w32tm /stripchartcan contact the server:
w32tm /stripchart /computer:ntp.metas.ch /samples:5 /dataonly
Tracking ntp.metas.ch [195.176.26.215:123].
Collecting 5 samples.

In the meantime I even completely wiped the disk and reinstalled windows 10 from scratch, but no luck.
I really don't know what else to do and where to look, since the error messages from windows are also not really helpful.
