Windows 10: Windows time not updating from local NTP server

Hi,


I have an issue with my current Windows 10 machines Windows 10 version 18363.592 not updating times from a local NTP server on my network.


I've set Windows to synchronise with an internet time server my local time server running on a fixed IP address 192.168.0.19, but my time is always wrong.


If I force Windows to update the time from the server then I receive the error " An error occurred while Windows was synchronising with 192.168.0.19. This operation returned because the timeout period expired."


I've checked that the time server is running correctly and other devices switches, NAS units etc. all sync correctly. I've been having this issue since the 1909 update was applied, this is happening on several machines.


I've run various NTP checking programmes and all of them report that they can see the time server, using port 123, and can obtain time settings from it, so I can't see that this would be a firewall issue on the machines.


I also have a VM of Windows 8 running on the NAS unit to deal with some legacy items that will not run on Windows 10, and Windows 8 can update its time from the NTP server.


Any ideas on how to fix this issue?

:)

 

About Microsoft having public NTP server

I suggest Microsoft to start its own public NTP server, which can be used ny people for syncing computer clocks on networks where NTP ports ate blocked.

Their current server is protected and uses only selected ports for time syncing in OS.

However, if it starts using port 80 or 443 then it will be easy for people to sync on restricted or secured networks.

Kindly let me know if such thing already exists.

Thank you.

 

Windows 7 can't sync its time with NTP server running on a Windows 10 PC

I am running an NTP server on a Windows 10 PC using the instructions at How to Create a Standalone NTP Server With Windows. The w32tm query output on the server looks correct and shows the server is configured (see below), and the
W32time service is running.

But I cannot set the time on other PCs using that as the Internet time server, not by name nor ip address. The client can ping the server by name or ip address fine. There are no firewalls involved; the clients and server are connected to the same router.
When trying to synchronize, they get "An error occurred while Windows was synchronizing with xxxxx. This operation returned because the timeout period expired." Tried restarting server and service.

Has anyone tried this and gotten it to work?
