This problem often occurs with some NTP servers, including and And there can be many reasons for this problem. Fortunately, you can easily fix it using the following methods.

What is causing the “Error Occurred While Windows was Synchronizing” issue?

Windows Time Server stuck in a limbo state: A common reason that causes this error is that Time Server is stuck in a state between open and closed (commonly referred to as “limbo state”). If this scenario applies, you can solve the problem by changing the startup state to automatic on the service screen and restarting the service.

Time server unavailable: Another common cause of this problem is when the time server you are trying to contact is unavailable due to scheduled maintenance or unexpected downtime. In this case, you can bypass the problem by using a different server.

W32 is not registered: If W32Time is not registered in your Windows installation, this is probably the cause of this error message. In this case, you can easily fix the problem with a series of commands that can stop the service, unregister it, and re-register it.

Router/modem incompatibility: Although rare, your router or modem may also be causing this particular problem. If this scenario applies, you can solve the problem by rebooting or resetting the appropriate network.

Faulty third-party firewall: An over-protected third-party firewall can also cause this error message. False positives can cause communication between your computer and the time server to stop. In this case, you can solve the problem by removing the third-party package that caused the problem.

Faulty CMOS battery: If the problem recurs after it is fixed, your system probably cannot remember changes made between system starts because of a faulty battery. In this case, you can solve the problem by opening the case and replacing the faulty CMOS battery on the motherboard.

Time update interval too long: It turns out that this problem can also occur because the default update interval is insufficient to communicate with the time server. In this case, you can solve the problem by making some changes to the registry.
