This exercise aims to demonstrate how to configure a domain controller with the FSMO role PDC Emulator (Primary Domain Controller) to synchronize time with an external time source (NTP server).
To begin, we’ll go over how time synchronization works in the Active Directory Domain Services (ADDS) forest:
All domain computers or member servers synchronize time with the nearest domain controller (in the client AD site) or with the domain controller with the PDC role (if AD sites are not configured); all domain controllers synchronize time with a domain controller PDC role holder.
PDC synchronizes time with itself by default, but you can configure it to synchronize with an Internet-based time source (NTP server).
You can manually or automatically configure time synchronization on the PDC.
1.Logon to TMDC03 as Techmentor\Administrator.
2. Open an administrative Command Prompt.
3. w32tm.exe /config /manualpeerlist:”0.pool.ntp.org,0x8 1.pool.ntp.org,0x8 2.pool.ntp.org,0x8″ /syncfromflags:manual /update
4. w32tm /config /reliable:yes.
5. net stop w32time && net start w32time.
6. w32tm /resync.
7. The list of current NTP sources is stored in the registry critical HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Parameters in the NtpServer parameter.
