Unable to sync time - The computer did not resync because no time data was available.
The environment is:
PDC emulator running WIn2019 and used as time source for the entire domain, UDP/123 allowed on the local firewall and PDC emulator since 25/10/2019
Reliable time source for PDC emulator is the Cesium atomic clocks from: http://pcdsh01.on.br/HoraLegalBrasileira.php (less than 1 second error on 10 MILLION years) and following the guidelines of the "authoratiative time server", running OK since then
Serveral Windows domain-members and some Linux machines (using ntp.conf pointing to the FQDN of the PDC emulator)
Occasionaly, some WIndows machines are getting 4 to 5 minutes late and the resync is impossible, i ended up setting clocks manually and some of then, on the next day, got to be late gain, 4-5 minutes
So, on my domain members i tried:
net stop w32time
net start w32time
w32tm /config /update
w32tm /resync /rediscover
net time \ntp /set /yes
w32tm /config /computer:ntp /update /syncfromflags:DOMHIER
w32tm /resync /computer:ntp
Sending resync command to ntp...
The computer did not resync because no time data was available.
The last error is particularly weird, because I can´t see any reason on why data couldn´t be available
Besides manual intervention, why can´t I just re-sync and set the cloks at the first attempt, why is sometimes so difficult to set time?
