All Domain Controllers in child Domains synchronize time with any Domain Controller with Parent Domain or with PDC Emulator of its own Domain.All domain controllers in the forest root domain synchronize time with the PDC Emulator FSMO role-holder.It is possible to override this configuration and bypass PDC emulator, but the default (and recommend) configuration is that all domain members should sync time with forest PDC emulator, directly or indirectly.
#Gomez peer zone activation time windows
This is because the Forest root domain PDC emulator is the one and only one-time source for all the Domain Controllers, member servers and windows based workstations for the entire forest. In Active Directory deployment, the only computer configured with a time server explicitly should be computer holding the PDC Emulator FSMO role in the forest root domain. NTP is implemented via UDP over port 123 and can operate in broadcast and multicast modes, or by direct queries.Īctive Directory Time Synchronization Architecture Network Time Protocol (NTP) is the default time synchronization protocol used by the Windows Time Service (WTS) in Windows servers and workstations. We also recommend checking this TechNet article, which gives a very good insight of the Windows Time Service:
#Gomez peer zone activation time how to
In this article, we would discuss the AD Time Synchronization architecture, how to configure an external time source and various other aspects of the Windows Time Service. Set wrong thus making it look like the most recent change. So it is important that changes made at a later actual time on one DC don’t get overwritten by similar changes on another DC, whose time is
In an Active Directory domain, it is very important for all clocks to be within 5 minutes of each other (by default) due to the implementation of the Kerberos protocol for authentication.Īlso, Active Directory uses multi-master replication model between Domain Controllers.
