Windows Server 2019 and Time Server, NTPServer synchronization issue

Question

Hi,

I have Domain with Windows Server 2019 and many Windows 10 Clients and Windows 11 Clients.

We have a big issue with Time synchronization Domain and Windows Clients.

Sometimes is 20 seconds or 1 minute with domain. I thin on the domain is the time correct, but on the Clients not.

I have added in the Registry on the domain the Ntpserver with our Firewall (IP address) Time

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters

NtpServer= Firewall (IP address)

But I have still the issue with Windows Clients. Is that maybe Firwall issue between Domain and Clienst?

I dont thing so, because the firewall between the Domain Client is disabled.

On the Clients I did run the following command

w32tm /query /status

w32tm /query /source (show me here my domain Controller)

Any Idea?

Regards

Hello,

Thank you for posting in Q&A forum.

To resolve the time synchronization issue between your domain and Windows clients, you can follow these steps:

1. Verify Time Synchronization: On both the domain controller and the client machines, If there is a significant time difference, use the w32tm /resync command to synchronize the time with their respective time sources.
2. Force Time Synchronization: On the affected client machine, open a command prompt and run the following commands:

net stop w32time

net start w32time

3. Check Group Policy Settings: - Ensure that the Group Policy for time synchronization is correctly configured. You can check the following policy: Computer Configuration > Administrative Templates > System > Windows Time Service > Time Providers - Ensure that the policy is set to synchronize with the domain controller.

I hope the information above is helpful.

Best regards
