Step1: Remove Time Synchronisation of Guest with Hostįollow the procedure if the host is Hyper-v Hostġ.

Do not restore a snapshot to a production domain controller (PDC).

Uncheck time synchronization of DC and virtual machines in VMware Tools configuration.

Uncheck time synchronization in the Integration Services if the DC and virtual servers are virtualized on Hyper-v.

Never sync a domain controller time with the virtual host.

Never put a virtualized domain controller in a saved state.

Only domain controller is your time provider and domain controller sync time with hardware time provider or internet time provider. You cannot have domain controller or hyper-v host or ESXi host as time provider.

There must be a unique time provider in your infrastructure.

These recommendations provide more accuracy and security to your domain.īefore you configure NTP Server and Client, you must consider the following for time Services for a virtualized Domain Controller and/or virtual machines.

Reduce your time correction settings for your servers and stand-alone clients.

When you configure the authoritative time server to sync with an Internet time source, there is no authentication between PDC and external time source.

Configure the authoritative time server to obtain the time from a hardware source.

All PDC emulator follow the hierarchy of domains in the selection of their in-bound time partner.

All secondary domain controllers and RODCs in a domain nominate the primary domain controller (PDC) as their in-bound time partner.

All client desktop computers and member servers nominate the authenticating domain controller as their in-bound time partner.

By default, Windows-based domain joined computers use the following hierarchy: In this hierarchy, the PDC emulator of Active Directory FSMO role is at the root of the forest becomes authoritative for the organization.

To ensure correct time usage, the Windows time service uses a hierarchical control of time services and avoids any loops in time hierarchy. Windows time services ensure that entire server and client fleet in an organization that are running the Microsoft operating system use a common and correct time. In my case i use an italian’s NTP server “”.The Time Service tool (W32tm) is a required protocol by the Kerberos authentication in Microsoft Active Directory. Now, because this is the only server that need to sync with an external time source, we need to set an NTP server an the “type” of protocol on NTP. īut before, we need do create a WMI filter to apply to identify and filter only the server that has the DomainRole property is set to 5 ( Primary Domain Controller)ĥ (0x5) Primary Domain Controller Administrative Templates>System>Windows Time Service>Time Providers Now we need to enable the server-side configuration and, to do this, we need to create another GPO linked to “Domain Controllers” OU.

Open Group Policy Management create and link to root tree a new GPO called “Time-Sync-to-DC”Įdit it and go to Computer Configuration >Administrative Templates>System>Windows Time Service>Time ProvidersĮnable the Windows NTP Client and edit “configure Windows NTP Client” like this : The PDC is where we need to forse clients to sync… Now before start, we have to create a GPO to force domain’s client to sync with the PDC’s role holder.

So, open the command prompt and issue this command to see the situation on a PC or a server…Īs we can see in this case this pc/server is using a “free” source to sync time.

Our goal is force clients time syncing with the PDC and set the PDC to sync to an external public NTP server. In this guide we are involved on the right configuration of time-sync in a Windows domain eviroment.
