I inherited an environment with a Windows 2012R2 Domain Controller (serverA) set as the NTP server. This server is going to be retired shortly for a new (separate) 2019 instance. The domain controller does not have the PDC Emulator role assigned to it.
The NTP server points at a separate NTP server outside of our immediate network. This NTP server it points at is not a public NTP server accessible over the internet. It's internal to the organization but not part of the network my environment resides in.
If I run w32tm /query /source
on any of the other servers in our environment (app, database, domain controllers) they reference our NTP server or one of the other domain controllers in our environment.
Where I'm getting confused or need clarification, is the registry setting for domain member servers reference time.windows.com,0x8 or time.windows.com,0x9 here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
- NtpServer
Only one domain controller has the registry value above set as the NTP server in our environment (serverA). Should this registry value for the domain member servers be set to the IP/host name of our domain controller (serverA)?
Before I perform any kind of migration I want to make sure I understand the current configuration so I can fix/resolve any issues. I'd appreciate any help or clarification!
