Does a PC automatically get its time from a Domain controller once it joins the domain?

hi guys,

If a PC joins a domain, will it automatically just get its time from the domain controller? Or is that something which needs to be pushed by the Domain Controllers via a policy?

Thanks

By default, all computers joined to domain uses PDC emulator to synchronize internal clock. You don´t need do anything to work.

This is not default behavior. If the clients are not configured to point directly to the PDC for its time source it will use ANY DC to get the time. This is still appropriate becasue with this method it is using the Hierarchy for the Time Source.

Time Source Hierarchy
External NTP Time Source
PDC
All Other Read/Write DC's
Client/Workstations

For all client to automatically talk to the PDC for all time source is done by a GPO. This GPO is not setup or enabled by default so the assumption would be (if you have not configured anything) when you clients are added to the domain Yes the time will Sync with the domain but it could sync with any of the domain controllers, which is completley fine.

The Domain Controllers get there Time from the PDC so the other DC times are correct.

See the link below for additional info in understanding the Time Source Hiearachy.
