NTP Time sync to Domain Server

Question

Hello,

Ok my setup is I have a Windows Server 2019 server. This server is part of my Domain, but is not a Domain Controller and cannot be one.

I then have a Windows 10 v21H2 client system.

What I am trying to do is to use the Windows Server as the NTP server for the Windows 10 client.

If I remove the Server from the domain, this works fine. I can make time changes on the client system and then reboot and see the system re-sync to the server.

However, once I put the Windows Server on the domain this no longer works. The client no longer is able to sync with the server.

Does anyone know why this is? Is there any fix to this?

I need the Client to sync to the server for log file purposes. We need to be able to see the logs on each system and they need to match exactly.

Thanks.

Answer 1

So I'd do a

netstat -aon>C:\netstat.txt

then look for a line in the file similar to

  UDP    0.0.0.0:123            *:*                                    256

then use Task Manager\Processes tab to see that the PID is for Windows Time service

then you can use prtqry tool to check from the 10 client.

Answer 2

So, not sure what happened, but I had to remove the client system to do another test. I then set it back up and pointed it to the Domain server and I am having no issues syncing now.

Thank you all for you help. I think I am all set for now.
