Are domain controllers automatically NTP servers?
No, Domain Controller can act as an NTP Server only just for domain-joined computers with Windows OS. If you want other devices to sync their times, you should set up and configure an NTP Server and tell your DC/DCs to sync its time with it.
How do I point my domain controller to NTP?
Suggested Actions
- Open Registry Editor(regedit.exe)
- Navigate to the following registry key: HKLM\System\CurrentControlSet\Services\W32Time\Parameters.
- To use a specific NTP source, modify the Type value to NTP.
How long does NTP take to synchronize?
about five minutes
Usually it takes about five minutes (five good samples) until a NTP server is accepted as synchronization source. Interestingly, this is also true for local reference clocks that have no delay at all by definition.
How do I sync my domain controller time with external time source?
Open Registry Editor(regedit.exe) Navigate to the following registry key: HKLM\System\CurrentControlSet\Services\W32Time\Parameters. To use a specific NTP source, modify the Type value to NTP. Modify the NtpServervalue to contain the NTP server to synchronize time with followed by 0x8, for example 131.107.
How do domain computers sync time?
If the computer is a member server or workstation within a domain, by default, it follows the AD DS hierarchy and synchronizes its time with a domain controller in its local domain that is currently running the Windows Time service.
How often does NTP sync Windows?
The date time of your PC (specific for windows) sync with one of the listed NTP server. This time sync happens every 7 days and with time.windows.com by default. You can also manually sync or update your time.
How do I know if my windows server is syncing with NTP?

- Click on the Windows button.
- In the “Search programs and files” box, type cmd and press Enter.
- If necessary, select cmd from the list of search results.
- In the command prompt window, enter w32tm /query /peers.
- Check that an entry is shown for each of the servers listed above.
Where does domain controller get time from?
On all computers joined to the Active Directory domain the closest domain controller is used as the default time source. In this case, the Type parameter must be set to NT5DS. If NTP is specified here, then your computer synchronizes time with an external source time (possibly on the Internet).
How to synchronize time with NTP server on Windows Server 2003?
Synchronize time with NTP server on Windows Server 2003 R2. 1 Open a command prompt (Windows Key + R) 2 In the Command Prompt window, type the following line, where peers is a comma-separated list of IP addresses of the appropriate time sources and press
Why can’t I synchronize with Windows Server 2003 domain controllers?
This problem may occur when your computer sends synchronization requests by using symmetric active mode. By default, Windows Server 2003 domain controllers are configured as time servers and use symmetric active mode to send synchronization requests. Some NTP servers that don’t run Windows respond only to requests that use client mode.
How do I synchronize the domain controller with an external time source?
To synchronize the domain controller with an external time source: Open a command prompt In the Command Prompt window, type the following line, where peers is a comma-separated list of IP addresses of the appropriate time sources, and press ENTER:
