An error occurred while windows was synchronizing with ошибка

Вы можете столкнуться с ошибкой синхронизации времени в Windows, когда ваш компьютер не может автоматически синхронизировать свое время с серверами времени time.microsoft.com в Интернете. Из-за некорректного времени на компьютере у вас может возникать ошибка «
Your clock is ahead/ Ваши Часы спешат (отстают)
» при открытии HTTPS сайтов Chrome (и в других браузерах), не корректно работать сторонние программы, и появляться различные другие неприятности.

Если попытаться вручную выполнить синхронизацию времени из панели управления Windows (Control Panel -> Date and Time -> Internet Time -> Change Settings -> Update now), появляется ошибка:

An error occurred while windows was synchronizing with time.windows.com. The peer is unreachable.

Также здесь может быть ошибка:

The peer is unresolved.

Проверьте, что у вас настроена автоматическая синхронизация времени с NTP серверами в Интернете. Перейдите в раздел Settings -> Time and Language -> Date and Time (можно перейти в этот раздел с помощью команды быстрого доступа по URI:
ms-settings:dateandtime
). Проверьте, что здесь включена опцию Set time automatically и выполните синхронизацию, нажав кнопку Sync now в разделе Additional settings.

Если синхронизация времени с Интернетом не работает, проверьте, с какого внешнего NTP сервера должен получить время ваш компьютер. Выполните команду:

w32tm /query /peers

По умолчанию компьютеры в рабочих группах (не присоединенные к домену Active Directory) настроены на получение времени с серверов time.windows.com.

Если при запуске этой команды появилась ошибка “The following error occurred: The service has not been started. (0x80070426)”, проверьте состояние службы Windows Time. Она должна быть настроена на автоматический или ручной запуск. Можете проверить состояние службы с помощью PowerShell или консоли services.msc:

Get-Service w32time| Select DisplayName,Status, ServiceName,StartType

Перезапустите службу:

Restart-Service -Name w32time

Если служба отключена, включите ее.

Проверьте, что с вашего компьютера доступен хост time.microsoft.com.

Сначала проверьте, что ваш компьютер может разрешить это имя в IP адрес:

nslookup time.windows.com

Проверьте доступность сервера с помощью ping:

ping time.windows.com

И затем проверьте, что сервер времени Microsoft доступен по порту NTP (UDP 123). Для проверки доступности UDP порта можно использовать утилиту portquery или можно напрямую обратиться к серверу и запросить у него текущее время:

w32tm /stripchart /computer:time.windows.com

Если команда вернет ошибку error: 0x800705B4, значить указанный NTP сервер не доступен. Проверьте, что в Windows открыт исходящий порт UDP/123 для протокола NTP (по умолчанию порт должен быть открыт). Вы можете принудительно открыть порт в Windows Defender Firewall с помощью PowerShell:

New-NetFirewallRule -DisplayName "AllowOutNTP" -Direction Outbound -Protocol UDP -RemotePort 123 -Action Allow
Enable-NetFirewallRule -DisplayName AllowOutNTP

Также убедитесь, что исходящий NTP трафик не блокируется на сетевом уровне (провайдера, вашего файервола или другими сетевыми устройствами).

Если этот NTP сервер не доступен, вы можете использовать другой NTP сервер.

Можно указать
time.nist.gov
или ближайший к вам NTP сервер, который можно получить на сайте
https://www.ntppool.org
.

Можно изменить адрес вашего NTP сервера с помощью командной строки:

w32tm /config /manualpeerlist:time.nist.gov,0x1 /syncfromflags:manual /reliable:yes /update

Перезапустите службу времени (в данном примере вы запустим несколько команд в одну строку):

net stop w32time && net start w32time

Затем выполните синхронизацию времени:

w32tm /config /update
w32tm /resync

Проверьте, что ваш компьютер успешно получил время с нового источника времени (NTP сервера):

w32tm /query /status

Если ничего не помогло, попробуйте полностью сбросить настройки службы Windows Time:

net stop w32time
w32tm /unregister
w32tm /register
net start w32time

Выполните синхронизацию времени:

w32tm /resync

Для автоматической синхронизации времени в Windows используется отдельно задание в планировщике Task Scheduler. Запустите консоль taskschd.msc и перейдите в раздел Task Scheduler (Local) -> Task Scheduler Library -> Microsoft -> Windows -> Time Synchronization. Проверьте, что задание SynchronizeTime включено.

Также вы можете проверить состояние задания Task Scheduler с помощью PowerShell:

Get-ScheduledTask SynchronizeTime

Чтобы включить его:

Get-ScheduledTask SynchronizeTime|Enable-ScheduledTask

Question

Issue: How to Fix “An Error Occurred While Windows Was Synchronizing With time.windows.com” Error on Windows 10?

Hello, all. Time synchronization fails with an error “An error occurred while windows was synchronizing with time.windows.com.” Windows Updates are not being downloaded either as they get stuck immediately. What solution do I have?

Solved Answer

Although one might think that Date and Time applet on Windows is necessary for the users solely to check the time or date, there are many other services, which strictly require Date and Time settings to be set correctly. For example, Windows Store apps may fail to download or the latest Windows Updates may not be offered to you.

To prevent Date and Time issues, Microsoft developed an Automatic clock synchronization service a long time ago. Automatic synchronization allows Windows OS^[1] to manage Date and Time settings according to the time zone. Additionally, Microsoft^[2] recommends people to synchronize time settings with a time.windows.com online server by following these steps:

• Right-click on Windows key and select Control Panel.
• Open Clock, Language and Region and click on Date and Time.
• Select Set the time and date and click on Internet time.
• Click Change settings and mark Synchronize with an Internet time server option.
• Finally, click Update now.

The problem is that sometimes Windows fails to synchronize with the time.windows.com server and delivers an error message “An error occurred while windows was synchronizing with time.windows.com.” The culprit of an issue is Windows Time service, which is not running for some reason. However, this problem is not a very uncommon one as Windows users have been discussing it in tech-related forums.^[3]

To fix “An Error Occurred While Windows Was Synchronizing With time.windows.com” error, you should change Windows Time service settings or restart the service.

Method 1. Change Windows Time service settings

• Click Windows key + R, type services.msc, and press OK.

  

• Find Windows Time service on the list and double-click it.
• Make sure that Startup type is set to Automatic.
• Now click Start, click Apply, and OK to save the changes.

If these steps did not help, try restarting Windows Time service.

• Reopen Windows Services window as explained above.
• If Windows Time service is started, stop it and set the Startup type to Automatic.
• After that, Start the service, click Apply, and OK.
• To confirm all the changes, reboot the system.

Method 2. Re-register Windows Time

If restarting Windows Time service did not help to fix “An Error Occurred While Windows Was Synchronizing With time.windows.com” error, try to re-register Windows Time using Command Prompt:

• If the command have been successfully executed, Command Prompt should deliver the following message: “The windows Time Service is starting. The windows time service was started successfully.”

Method 3. Run an SFC and DISM scan with Command Prompt

• Go to your Windows search zone and type in cmd.
• Make sure that you are using Command Prompt as Administrator.

  

• Once the black dialogue box shows up, type in this text and hit Enter: Sfc /scannow sfc /scannow /offbootdir=c:\ /offwindir=c:\windows.
• When the process is completed, reboot your machine.
• After that, open Command Prompt again and type in the following lines by pressing Enter after each one: 1) Dism /Online /Cleanup-Image /CheckHealth 2) Dism /Online /Cleanup-Image /ScanHealth 3) Dism /Online /Cleanup-Image /RestoreHealth.
• If the command has already finished running but the problem still occurs on your computer, try typing in this one:

Dism /Image:C:\offline /Cleanup-Image /RestoreHealth /Source:c:\test\mount\windows Dism /Online /Cleanup-Image /RestoreHealth /Source:c:\test\mount\windows /LimitAccess

Important: C:\RepairSource\Windows needs to be rewritten with your repair source’s location.

Method 4. Try using another synchronization server

• Find the Windows Control Panel and access it.
• Type in Date and Time and press on it.
• Find the Internet Time tab in the next window and select the “Change settings” option.
• Ensure that you there is a checkmark neer this option: Synchronize with an Internet time server.
• Scroll through the server dropdown menu until you find time.nist.gov and choose it.

  

• After that, select Update now —> OK and wait until the process is finished.

Method 5. Disable your Firewall program for some time

• Find the Control Panel.

  

• Click on the System and Security section in your Control Panel and press on Windows Firewall.

The ‘Error Occurred While Windows was Synchronizing’ error most commonly occurs when Windows users try to sync their time automatically by attempting to use the Windows menu to connect with an NTP server. In most documented cases, the error message will appear with time.windows.com, time.nist.gov, and every other NTP server.

What’s causing the ‘Error Occurred While Windows was Synchronizing’ issue?

We have included several methods to address this issue. We suggest that you follow every Method listed below until the issue is resolved.

1. Restart the Windows Time service

As it turns out, the number one reason why this issue will occur is due to the fact that the Windows Time service is not running or becomes stuck into a limbo state. This issue is much more common than you might expect – A lot of Windows 7, Windows 8.1 and Windows 10 users have been complaining that this service has the habit of failing to sync up even if it’s running properly.

Several affected users that encountered this issue have confirmed that the issue was resolved after they accessed the Services window and changed the status to Automatic or restarting the service, forcing it to reinitialize.

Here’s a quick guide on doing this on a Windows computer:

Note: The steps below should be applicable regardless of the culprit that ends up causing the issue.

1. Press Windows key + R to open up a Run dialog box. Next, type ‘services.msc’ and press Enter to open up the Service screen. If you are prompted by the UAC (User Account Control) prompt, click Yes to grant administrative privileges.
2. Once you’re inside the Services screen, move to the right-section and scroll down through the list of services until you locate the Windows Time service. When you see it, right-click on it and choose Properties from the newly appeared context menu.
3. Now that you’re inside the Properties menu of Windows Time, select the General tab from the top of the screen and use the drop-down menu associated with the Startup type to change it to Automatic.
4. Next, click on Stop to temporarily stop the service, then click on Start to restart the Windows Start service.
5. Click Apply to save the changes, then repeat the operation and see if the problem has been resolved.

In case you’re still encountering the same ‘Error Occurred While Windows was Synchronizing’ issue, move down to the next method below.

2. Use a different server

If the issue only started to occur recently, it’s also possible that you’re encountering this issue due to the fact that the time server that you’re currently trying to access is inaccessible due to an unexpected issue or due to a scheduled maintenance period.

If this scenario is applicable, you can fix the issue by accessing the Internet Time settings and hanging the default values so that a different server is used when your computer needs to Syncronize the Internet time.

Here’s a quick guide on how to do this:

1. Press Windows key + R to open up a Run dialog box. Inside the text box, type ‘timedate.cpl’ and press Enter to open up the Date and Time server.
2. Once you’re inside the correct window, select the Internet Time from the horizontal menu at the top, then click on the Change Settings button below. When you’re prompted by the UAC (User Account Control), click Yes to grant administrative privileges.
3. Inside the Internet Time Settings window, start by checking the box associated with Synchronize with an Internet time server. Next, expand the drop-down menu associated with Server and set it to time.nist.gov.

   Note: If the time server was already failing with time.nist.gov, set it to time.windows.com.

4. Click on Update Now to attempt to synchronize the Internet time server once again.
5. See if the process manages to complete without the same error message.

In case the same error ‘Error Occurred While Windows was Synchronizing’ error message is still occurring, move down to the next potential fix below.

3. Re-register W32Time via CMD

Another fix that might potentially help you in fixing the ‘Error Occurred While Windows was Synchronizing’ error message is to use an elevated CMD prompt to re-register the W32Time service.

Several affected users that have encountered this issue before have confirmed that a series of commands finally allowed them to force the time server to update automatically. But keep in mind that before you can re-register the time service, you will need to disable it first. Luckily, you can do the entire process from a single elevated CMD.

Here’s what you need to do:

1. Press Windows key + R to open up a Run dialog box. Next, type ‘cmd’ and press Ctrl + Shift + Enter to open up an elevated CMD window. When you see the User Account Control (UAC) window, click Yes to grant administrative privileges.
2. Once  you’re inside the elevated terminal prompt, type the following commands in order and press Enter after each one to stop the time service, re-register w32time service and force the service to update itself:

   net stop w32time 
   w32tm /unregister
    w32tm /register 
   net start w32time 
   w32tm /config /manualpeerlist:pool.ntp.org /syncfromflags:manual /update

3. In case you get the following success message, it means that every command has been successfully processed:

   C:Documents and Settingsuser>net stop w32time
   The Windows Time service is stopping. The Windows Time service was stopped successfully.
   C:Documents and Settingsuser>w32tm /unregister
   W32Time successfully registered.
   C:Documents and Settingsuser>w32tm /register
   W32Time successfully registered.
   C:Documents and Settingsuser>net start w32time
   The Windows Time service is starting. The Windows Time service was started successfully.
   C:Documents and Settingsuser>w32tm /config /manualpeerlist:pool.ntp.org /update
   The command completed successfully.

4. If the operation is completed successfully, restart your machine and see if the issue is resolved at the next system startup.

In case the same ‘Error Occurred While Windows was Synchronizing’ problem is still occurring, move down to the next potential fix below.

4. Restart your Router/Modem

As it turns out, another common problem that might be responsible for the apparition of the ‘Error Occurred While Windows was Synchronizing’ error is router/modem stuck in a limbo state. Whenever this happens, chances are the time server cannot be reached, so this error will be thrown as a result.

If this scenario is applicable, the easiest way to get the issue resolved is to force your network to refresh.

To ensure that you start by the less-intrusive approach and you don’t make any long-lasting changes to your network credentials, you should start by performing a router reboot. To do this, simply press the dedicated button (if possible), or press the ON  / OFF button twice to initiate a network reboot.  Alternatively, you can simply physically disconnect the power cable from the power outlet, forcing the network to restart.

If that doesn’t work, you should move forward by trying to do a complete modem or router reset. But keep in mind that this operation might also reset the custom login credentials of your router address. Even more, any other network adjustments that you previously made might also be lost.

Note: With most router manufacturers, the login credentials for your router will be reverted back to admin (for both username and password.

To perform a router/modem reset, simply press the reset button and keep it pressed for at least 10 seconds or until you see all the front LED flashing at the same time.  That’s how you know that the reset procedure was completed.

Note: Keep in mind that with some models, the reset button is inaccessible without a sharp object like a needle, toothpick or a similar object.

If you already did this and you’re still encountering the same ‘Error Occurred While Windows was Synchronizing’ error, move down to the next potential fix below.

5. Disable 3rd party firewall

As it turns out, another responsible culprit that might be responsible for the ‘Error Occurred While Windows was Synchronizing’ error is an overprotective firewall suite. In some documented cases, this error appeared due to the fact that the 3rd party firewall was interrupting the connection between the time server and the end-user computer due to a false positive.

If this scenario is applicable, you can fix the issue easily by uninstalling the firewall that is causing the issue and reverting back to the default firewall (Windows Firewall).

Note: Keep in mind that simply disabling the real-time protection of your AV will not resolve the issue. It’s likely that the same security rules will remain in place despite the modification.

Here’s a quick guide on making sure that the external firewall no longer ends up creating the ‘Error Occurred While Windows was Synchronizing’ error:

1. Press Windows key + R to open up a Run dialog box. Next, type ‘appwiz.cpl’ and press Enter to open up the Programs and Features window.
2. Once you’re inside the Programs and Features screen, scroll down through the list of installed applications and locate the 3rd party firewall that you’re using. When you see it, right-click on it and choose Uninstall from the next context menu.
3. Once you see the uninstallation window, follow the on-screen prompts to complete the process of uninstalling the 3rd party firewall.
4. Restart your computer and see if the problem is fixed at the next computer startup.

In case you’re still seeing the ‘Error Occurred While Windows was Synchronizing’ error, move down to the next potential fix below.

6. Replace CMOS Battery

If this issue is recurring, meaning you fix the issue but the problem returns swiftly the next time you start your computer, chances are the issue is being caused by a faulty CMOS battery. This is a critical motherboard component that’s typically a CR2032 button cell.

The CMOS (Complementary Metal Oxide Semiconductor) battery (also known as RTC or NVRAM) is responsible for storing information ranging from time and date to system hardware settings. If your computer is unable to maintain the date & time between startups, it’s typically because of this component.

In case you suspect that you might be dealing with a faulty CMOS battery, you can fix the issue by clearing it once or replacing it altogether. Here’s a quick guide on doing this:

1. Turn off your computer and ensure that it’s no longer plugged into a power outlet.
2. Next, remove the side cover and equip your main hand with a static wristband if you have one at the ready.
   Note: A Static wristband will make sure that you are grounded to the frame and static electricity doesn’t end up producing damage to your PC components.
3. Look at your motherboard and identify the CMOS battery. Once you see it, use your fingernail or a non-conductive screwdriver to remove it from its slot.

   Note: If you have a spare battery around, replace the current one to ensure that you don’t encounter this issue again. Else, clean it thoroughly (and the slow) to ensure that there aren’t any connectivity issues.
4. Wait for a couple of minutes before putting them back case back and powering your computer again. At the next startup, return to the Date & Time window and attempt to update again, then restart again and see if the change is preserved.

If the same ‘Error Occurred While Windows was Synchronizing’ error is still happening, move to the final method below.

7. Adjust the updating interval

In some rare circumstances, you might encounter this particular issue due to the fact that a registry key is preventing date & time from refreshing at regular intervals. In case this scenario is applicable, it’s possible that the time.windows.com, time.nist.gov and any other NTP server might trigger the ‘Error Occurred While Windows was Synchronizing’ error due to the fact that it’s not unable to update the value again.

In this case, you should be able to fix the issue by changing the update interval to the next compatible value. Here’s a quick guide on doing this from using Registry Editor:

1. Press Windows key + R to open up a Run dialog box. Next, type ‘regedit’ and press Enter to open up the Registry Editor. When prompted by the UAC (User Account Control), click Yes to grant administrative privileges.
2. Once you’re inside the Registry Editor, use the left-hand section to navigate to the following location:

   HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeTimeProvidersNtpClient

   Note: You can also paste the exact location directly into the navigation bar to get there instantly.

3. Once you’re in the correct location,  move down to the right-section and double-click on SpecialPoolInterval.
4. Then, set the Base section to Decimal, then modify the default Value to 86400.

   Note: Changing the Value to 86400 ensures that the date and time will get updated after each day.

5. Close Registry Editor and restart your computer to allow the modifications to take effect.
