Windows ntp time sync command line

You cannot ignore the mentioned error message "The computer did not resync because the required time change was too big. Or, did YOU find any working solution to the original problem?? And why are you writing "blindly"? If you would take a short time to read through then you could see the exporting and importing the original data of these values, what is a bit far from doing something "blindly".

You should have this script change the values to disabled, force an update, and then change them back to recommended values. Twisty has valid points that do not really focus on the issue raised by NeverQuit In essence, the Registry values MaxNegPhaseCorrection and MaxPosPhaseCorrection exist to stop the W32Time service from applying dramatic changes to current time [in circumstances such as an external time source going badly awry] However, if some issue occurs that leads to a PDCe drifting rapidly from a reliable time source, then the correction controls will prevent w32tm fixing the big drift.

I still encourage including an explanation of what these two settings do as they're a key feature of your answer and it's important that an admin be aware that should they put these settings in place permanently they would configure their system to accept any time change, no matter how large, which could break Kerberos and other important network services.

The time syncronization does succeed eventually, just not in a timely and reliable manner. Comotion Comotion 1. Try in this order. Works all the time. I had to wait about 10 minutes between the first and second commands because of a The following error occurred: The specified service has been marked for deletion.

If you have a computer with multiple network adapters is multi-homed , you cannot enable the Windows Time service based on a network adapter. You can use the command-line tool W32tm. Membership in the local Administrators group is required to run W32tm. This option might be used more than once. Computer names are separated by commas, with no spaces. The default value is 3. The allowed range is If not specified, the local computer will resynchronize. Otherwise, wait for resynchronization to complete before returning.

This is used for compatibility purposes. The default is 2 seconds. If not specified, the default is the local computer. When specifying multiple peers, this option must be enclosed in quotes.

This setting is only meaningful on domain controllers. YES : This computer is a reliable time service. NO : This computer is not a reliable time service. If not specified, the default value is the local computer. In verbose mode, display the undefined or unused setting too. Valid values are 0 to A range of numbers is valid, in addition to single numbers, such as ,, Value is for logging all information.

Set client to use two time servers To set a client computer to point to two different time servers, one named ntpserver. To configure a client computer that is currently synchronizing time using a manually-specified computer to synchronize time automatically from the AD domain hierarchy, run the following following:.

To check a client configuration from a Windows-based client computer that has a host name of contosoW1 , run the following command:.

The output of this command displays a list of W32time configuration parameters that are set for the client. Windows Server has improved the time synchronization algorithms to align with RFC specifications. Therefore, if you want to set the local time client to point to multiple peers, we recommended that you prepare three or more different time servers.

If you have only two time servers, you should specify the Ntpserver UseAsFallbackOnly flag 0x2 to de-prioritize one of them. For example, if you want to prioritize ntpserver. Additionally, you can run the following command and read the value of NtpServer in the output:.

In order for W32tm. Then, to adjust the computer clock by using the clock rate, W32tm. This algorithm varies depending on the version of Windows:. MaxAllowedPhaseOffset is configurable in the registry.

However, the registry parameter is measured in seconds instead of clock ticks. This command produces output that resembles the following. The output presents the poll interval in both clock ticks and in seconds. The equations use the value measured in seconds the value in parentheses. The output presents the clock rate in seconds.

To see the SystemClockRate value in clock ticks, use the following formula:. For example, if SystemClockRate is 0. For full descriptions of the configurable parameters and their default values, see Config entries later in this article. The following examples show how to apply these calculations for Windows Server R2 and earlier versions.

In this case, if you want to set the clock back slowly, you would also have to adjust the values of PhaseCorrectRate or UpdateInterval in the registry to make sure that the equation result is TRUE.

The Windows Time service stores a number of configuration properties as registry entries. It stores configuration information that the policies define in the Windows registry, and then uses those registry entries to configure the registry entries specific to the Windows Time service. As a result, the values defined by Group Policy overwrite any pre-existing values in the Windows Time service section of the registry.

Some of the preset GPO settings differ from the corresponding default Windows Time service registry entries. Windows loads these settings into the policy area of the registry under the following subkey:. Then Windows uses the policy settings to configure the related Windows Time service registry entries under the following subkey:.

The following table lists the policies that you can configure for the Windows Time service, and the registry subkeys that those policies affect. When you remove a Group Policy setting, Windows removes the corresponding entry from the policy area of the registry. This information is provided as a reference for use in troubleshooting and validation. Windows registry keys are used by W32Time to store critical information.

Don't change these values. Modifications to the registry are not validated by the registry editor or by Windows before they are applied. If the registry contains invalid values, Windows may experience unrecoverable errors.

Some of the parameters in the registry are measured in clock ticks and some are measured in seconds. To convert the time from clock ticks to seconds, use these conversion factors:. Note Zero is not a valid value for the FrequencyCorrectRate registry entry. HoldPeriod All versions Controls the period of time for which spike detection is disabled in order to bring the local clock into synchronization quickly.

Method 3: Follow the steps mentioned below. Type each one of the command below and press enter. Hope it helps. How satisfied are you with this reply? Thanks for your feedback, it helps us improve the site.

In reply to A. User's post on October 16, As for Method 2, Windows 10 doesn't even show an Internet Time tab. Again, Method 3 is not going to be useful because I certainly won't be doing that every hour! I appreciate your trying to answer my question, but I need a different kind of answer.

Did not work. The time is still 2 hours fast. User's post on October 19, Dave, If you are still interested in an automatic time sync, I use this solution by Rob van der Woude on both Windows 7 and Windows This appears to be a permissions issue.

Clearly a bug, err I mean "feature" in Windows In reply to agardk's post on June 11, An Admin account needs to invoke its Admin privileges to have any effect. An Admin account is just a Standard user account except where this is done. Add a comment. Active Oldest Votes. Dousti 3, 6 6 gold badges 33 33 silver badges 47 47 bronze badges.

I have a workstation that is domain joined so time settings "Are managed by your organisation" but is is being used away from the domain at the moment.

Windows time service already started. It runs successfully without error. But time was not change. It make me crazy. Kayasax — Nick Dong.

Any help? Kayasax Found solution as per blog.
