To configure an authoritative NTP Time Server (on Windows Server Domain Controller) to synchronize with an external NTP time source, edit the following Windows registry entries:

Change the time server type to NTP
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type
Set to NTP
NTP stands for Network Time Protocol

Set AnnounceFlags to 5
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags
Set to 5
Announce flag values:
0 Timeserv_Announce_No, Reliable_Timeserv_Announce_No. The domain controller does not advertise time service.
1 Timeserv_Announce_Yes. The domain controller always advertises time service.
2 Timeserv_Announce_Auto. The domain controller automatically determines whether it should advertise time service.
4 Reliable_Timeserv_Announce_Yes. The domain controller will always advertise reliable time service.
8 Reliable_Timeserv_Announce_Auto. The domain controller automatically determines whether it should advertise reliable time service.
Flag 5 (1+4) means "The domain controller always advertises time service" and "The domain controller will always advertise reliable time service".
