Hi,
I have synchronization problems in my windows server who is primay domain controler.
This i am running:
net stop w32time
w32tm /unregister
w32tm /register
Net start w32time
w32tm /config /update /manualpeerlist:"0.pool.ntp.org" /syncfromflags:MANUAL
w32tm /config /update
net stop w32time && net start w32time
w32tm /resync /rediscover
And last command give my this error
the computer did not resync because no time data was available
.
I check the GPOs, Restart the service, restart the server and nothing works. I use other manualpeerlist and neither. The resync always failed with same error.

New problem or it has never worked? Might try a different time source.

I use different ip of the web and the same problem.
This is the first time we have tried to synchronize the time with an external server
Ok, most likely there is something blocking UDP port 123 in at least one direction. I remember pulling my hair out with this one some time back and it turned out to be the ISP blocking inbound.
--please don't forget to upvote and Accept as answer if the reply is helpful--
In the windows server firewall there is a rule created for outbound / inbound port 123 Active Directory Domain Controller - W32Time (NTP-UDP-In)
What should I request from my ISP? On this issue I am lost.
I have a small office with some servers and computers.
The windows firewall would not be blocking by default, its also a simple test to disable. Also, you didn't mention but if this were a virtual machine then make sure time sync is turned off in integration services. As to ISP you could look for documentation such as this.
