W32Time Service Accuracy Please bear in mind that the Windows W32Time service is not a full featured, accurate service for time sensitive application requirements, nor will Microsoft support it as such. Otherwise, this computer will function as a time an authorized source in the domain hierarchy. Time service configuration and status I suspect that w32tm /query /status well the state 'Pending' is telling me that the target system is not reaching out to, or getting a reply from the ntp pool You can ping it means that it can physically reach something that is responding The timenistgov should respond I wonder if you made a special allowance for the ntporgWindows Time Sync Command To. Configure the DC according to the configuration sections above depending on if it’s a PDC Emulator or non-PDC Emulator. Start the w32time service, type 'net start w32time' without quotes. Make your PDC a reliable time source for the clients, type 'w32tm /config /reliable:yes' without quotes. Either configure a reliable time service in the root domain, or manually configure the AD PDC it is recommended that you synchronize with an external time source. Configure the external time sources, type 'w32tm /config /syncfromflags:manual /manualpeerlist:' without quotes. As shown in Figure 2.7, select the This Domain Controller or AD LDS instance, enter the name of the DC. W32tm /query /configuration on the DC's which are not the PDC return:Ĭ:\Windows\system32>w32tm /query /configurationĭllName: C:\Windows\system32\w32time.dll (Local)ĪllowNonstandardModeCombinations: 1 (Local)ĭllName: C:\Windows\System32\vmictimeprovider.Time Provider NtpClient: This computer, but it has been configured to determine the time source by using the domain hierarchy, because it is the AD PDC emulator for the domain in the forest of the route, time source on the domain hierarchy you do not have a computer to be used as. Configuring the Active Directory Infrastructure.
#MANUALLY CONFIGURE THE AD PDC TO EXTERNAL TIME WINDOWS 7#
I am unsure how the DC's and the windows 7 clients are getting this information, it seems not be via DHCP or Group Policy. If I do C:\> w32tm /query /source on my other two Domain controllers they report back correctly with the PDC name.Ĭlients when using the same query report back any of the DC's. Synchronizing time on the domain controller(s) with the external source. Start the w32time service: C:\>net start w32time w32tm /config /manualpeerlist:0.uk. /syncfromflags:manual. You can configure time synchronization on the PDC manually or using a GPO. Education 6 hours ago PDC synchronizes time with itself by default, or you can configure it to synchronize with an external time source on the Internet (NTP server). I typically will use the same external NTP source as I configure on my PDC role holder. Configuring DC for Sync Time with External NTP Server. But you need to set the correct pools to synchronize from on your PDC. And what about the PDC (primary domain controller) Where does he synchronize his time from The answer is, he synchronizes from an internet pool. The domain controller itself synchronizes his time from the PDC (primary domain controller). Made PDC a reliable time source for the clients. I can understand wanting to manually sync non domain members and such though. Clients and servers in a domain/forest synchronizes her time from a domain controller. If an external time source is not configured or used for this computer, you may choose to disable the NtpClient.Ĭonfigure external time sources, type: C:\> w32tm /config /syncfromflags:manual /manualpeerlist:”0.uk.,1.uk. g,2.uk.,3.uk.”

To configure a Windows PDC to synchronise with an external NTP server requires registry entry changes. Applies to: Microsoft Windows Server 2008 Microsoft Windows Server 2003.

Otherwise, this machine will function as the authoritative time source in the domain hierarchy. Only the PDC needs to be configured to synchronize to an external time reference. It is recommended that you either configure a reliable time service in the root domain, or manually configure the AD PDC to synchronize with an external time source. Time Provider NtpClient: This machine is configured to use the domain hierarchy to determine its time source, but it is the AD PDC emulator for the domain at the root of the forest, so there is no machine above it in the domain hierarchy to use as a time source.
