Time keeps changing - win7 workstation

ScreenshotHey all, we have a windows domain environment with Server 2016 - now on one machine (w7 pro machine) - the time keeps changing. The domain controller and time on the other workstations is fine.

How would i fix that?

check the region settings and see if it is the same time zone - also what is the difference (an hour, 15 minutes, etc)

It keeps change to a few hours back and forth, time zone is correct. Seems to fail syncing with the DC.

The computer should be set to sync with the DC not time.windows.com because the gateway firewall rules may block that.  Regardless, the workstations should always sync with the DC not external NTP server.

The DC is the NTP server for the domain by default so that service should be running already.

If it fails to sync with the DC then it may be caused by Windows firewall blocking it.  Try turning off the firewall for testing or create a rule for NTP port 123 (UDP)

Also check to ensure the Windows Time service is running on the W7 machine: https://computerstepbystep.com/windows_time_service.html
