Hello All,

we have NTP server which is windows 10 installed and in registry settings we configured NTP server (10.10.10.10) to get time source from external time source.
It is working fine.

In AD, We have written GPO, across the domain all the devices should sync with NTP server.

NTP server :
C:\Windows\system32>w32tm /resync
Sending resync command to local computer
Successfull

ADC server :
C:\Windows\system32>w32tm /resync
Sending resync command to local computer
The computer did not resync because no time data was available.

Unable to find solution. Please help

    But i want devices to get the time from NTP server itself.

    This isn't a recommended or supported method.

    w32tm /unregister
    net stop w32time
    w32tm /register
    net start w32time
    w32tm /config /manualpeerlist:<ntp ip address> /syncfromflags:manual /reliable:yes /update
    net stop w32time
    net start w32time
    then check
    w32tm /query /source
    w32tm /query /configuration

    I have set my GPO to use NTP server for time synchronization all devices including domain controllers.

    If we set "NT5DS" it means it should get the time from DC right ??
    But i want devices to get the time from NTP server itself.

    So Which is recommended method ?

    Internal NTP server sync with External time servers

    AD sync with NTP server

    Domain computers sync with AD server ?

    Domain computers > AD > NTP server > External time servers

    ???
