Domain Controller Sync Time To External Source

You can use the command lines in this article to configure both options since the only difference is the time server address.

Domain controller sync time to external source. All domain computers or member servers synchronize time. Run an elevated command prompt. An external source can be either a time server out on the internet or a hardware appliance if it s a highly secure environment and outside communication is restricted. Here we will configure your primary domain controller pdc to connect to an external source to keep your time synchronized up with the rest of the world.

This should fix time issues across the domain if run on the correct dc. How do you sync the computer to the same time as the cell phone nist external time source and make sure that all computers on your network have the same time as the domain controller. To make sure that time is reliable within the forest set only pdc emulator in the root of the forest to synchronize with an external time source. First i am going to reference much of the information provided by.

Now the thing is that this domain controller also needs to synchronize it s clock but this time with an external source or ntp server. First determine from a client computer which computer is the authority for your time server. In this article we will take a look on how to configure a domain controller with the fsmo role pdc emulator primary domain controller to synchronize time with the external time source ntp server. By changing the primary dc s time source to an external source the changes will be replicated from the pdc to other clients in your domain.

To do so on the client pc open a command prompt and run the command. I have a virtual dc that holds all 5 roles and it is currently set to sync it s time with the cmos on the host. First of all we remind you how time synchronization works in the active directory forest. Domain controller that sits in the root of the forest and has pdc emulator role assigned to it represents the time authority to all other members of the forest.

This is usually your primary domain controller. Limiting the amount of bandwidth needed to synchronize with an external source. In case you have multiple domains configure the pdc emulator. To use w32tim to set an external authoritative ntp server on a domain controller primary or secondary windows server or windows workstation follow these steps.

By default all machines in the domain will sync time from the domain controller which is the internal time server if you have more than one dc then time will sync from the dc that holds the pdc emulator fsmo role. To check which dc is pdc emulator in your domain you need to run netdom query fsmo command like so.
