Using the Command Prompt to set time server
If you prefer using the command line, you can also set the time server in Windows 2008 R2 by using the Command Prompt. Follow these steps to set the time server:
Step 1: Open the Command Prompt as an Administrator. To do this, right-click on the Command Prompt icon and select “Run as Administrator”.
Step 2: Type the following command and press Enter: w32tm /config /manualpeerlist:pool.ntp.org /syncfromflags:manual /reliable:yes /update
This command sets the time server to pool.ntp.org, which is a reliable time source on the internet. You can replace this with any other time server of your choice.
Step 3: Type the following command and press Enter: w32tm /resync /nowait
This command forces the computer to synchronize with the new time server immediately without waiting for the next scheduled synchronization.
Step 4: Verify that the time synchronization was successful by typing the following command and pressing Enter: w32tm /query /status
This command displays the current time source and synchronization status. If the synchronization was successful, the output should show “Source: pool.ntp.org”.
Step 1: Open Command Prompt with administrative privileges
In order to use the Command Prompt to set a time server on Windows 2008 R2, you will need to open the Command Prompt with administrative privileges. This will allow you to execute the necessary commands to set the time server. To do this, click on the “Start” button and type “cmd” in the search box.

Common issues with time synchronization and how to fix them
Inaccurate time synchronization: One of the most common issues with time synchronization is inaccurate time. This can happen due to several reasons, including incorrect configuration or the use of an unreliable time source. To fix this issue, check the configuration and use a reliable time source.
Firewall blocking time synchronization: Another common issue is when a firewall is blocking time synchronization traffic. This can prevent the system from receiving time updates and lead to inaccurate time. To fix this, you need to configure the firewall to allow time synchronization traffic.
Failure to sync with the time server: Sometimes, the system fails to synchronize with the time server. This can happen due to several reasons, including network connectivity issues, incorrect configuration, or issues with the time server. To fix this, check the network connectivity, reconfigure the time server settings, or choose a different time server.
Time synchronization errors and their potential causes
“The computer did not resync because no time data was available.”
This error message indicates that the computer was unable to find a time source to synchronize with. This could be due to several reasons such as a firewall blocking the connection, the time server being unavailable or the time source being unreliable.
“The computer did not resync because the required time change was too big.”
This error message indicates that the computer clock is too far out of sync with the time server to be corrected. This could be due to a misconfiguration of the time server or the computer’s clock being manually changed.
“The computer did not resync because the time difference was too small.”
This error message indicates that the time difference between the computer clock and the time server is too small to require a synchronization. This could be due to the time server being configured to synchronize only at specific intervals.
Network Time Protocol (NTP) vs. Windows Time Service (W32Time)
Network Time Protocol (NTP) is a protocol used to synchronize the clocks of computer systems over a network. NTP is an open standard that has been widely adopted and is supported by a large number of devices and operating systems.
Windows Time Service (W32Time) is the time synchronization service built into Windows operating systems. It is based on the Simple Network Time Protocol (SNTP) and is designed to synchronize the clocks of Windows-based computers within a domain.
While both NTP and W32Time can be used to synchronize time on Windows-based computers, there are some important differences between them. NTP is more accurate and reliable, as it uses more complex algorithms and can adjust for network latency and other factors that can affect clock synchronization. W32Time, on the other hand, is simpler to configure and is better suited for use in smaller networks or where high accuracy is not a critical requirement.
Overview of NTP and W32Time
Network Time Protocol (NTP) is a protocol used for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. It is widely used and provides a highly accurate time reference.
Windows Time Service (W32Time) is a time synchronization service used by Windows operating systems to synchronize time on client computers with a time server. W32Time is based on NTP and can be used to synchronize time with an NTP server or with another Windows computer acting as a time server.
Both NTP and W32Time are important for ensuring accurate time synchronization in a network environment. However, there are some differences between the two protocols that should be considered when choosing which one to use in a specific environment.
Advantages of using NTP over W32Time
Accuracy: NTP is more accurate than W32Time because it can synchronize time to within a few milliseconds, while W32Time can only synchronize to within a few seconds. This level of accuracy is essential for organizations that require precise timekeeping.
Reliability: NTP is more reliable than W32Time because it uses multiple time sources to synchronize time, which means that if one source fails, the system can still synchronize time with the remaining sources. W32Time, on the other hand, relies on a single time source, which can lead to synchronization errors if that source fails.
Flexibility: NTP is more flexible than W32Time because it can be configured to work with a wide range of devices and operating systems. This makes it easier to integrate into existing networks and ensures that time synchronization is consistent across all devices.
When to use W32Time instead of NTP
Compatibility: W32Time is built into Windows and requires no additional software, making it the default time synchronization protocol for Windows systems. It is also compatible with Active Directory, making it the preferred option for Windows networks with domain controllers.
Simplicity: W32Time is simpler to set up and manage compared to NTP. It uses a hierarchical time synchronization model, which allows clients to synchronize time with domain controllers, while domain controllers synchronize time with the primary domain controller.
Accuracy: While NTP is generally considered to be more accurate than W32Time, the accuracy of W32Time can be improved by configuring it to synchronize time with external time sources, such as atomic clocks or GPS devices.
Verifying time synchronization with Event Viewer
Introduction
One of the key tasks in maintaining an accurate time source for your Windows 2008 R2 network is verifying that your servers and clients are properly synchronized. Fortunately, Windows provides several tools to help you with this, including the Event Viewer.Checking the Event Viewer for time-related errors
The Event Viewer is an excellent tool for checking the time synchronization status of your network. When a time-related error occurs, it is often recorded in the Event Viewer. You can use the Event Viewer to check for errors and determine their causes.Verifying successful time synchronization
To verify that your servers and clients are successfully synchronizing with your chosen time source, you can use the Event Viewer to check for synchronization events. These events indicate that time synchronization has occurred successfully.Manually triggering time synchronization
If you need to test your time synchronization settings or force an immediate synchronization, you can use the command line tool w32tm to manually trigger time synchronization on a Windows 2008 R2 server or client. Once synchronization is complete, you can use the Event Viewer to verify that it was successful.Step 1: Open Event Viewer
To verify time synchronization with Event Viewer, the first step is to open the Event Viewer application. This can be done by using the search function in the Start menu or by navigating to the Administrative Tools folder in the Control Panel. Once the Event Viewer is open, expand the Windows Logs folder in the left pane and click on the System log to view time-related events.
Note: It is recommended to check for time synchronization errors after configuring the time settings or changing the time source.
Tip: Use the filter option in the Event Viewer to search for specific time synchronization events, such as those related to time source changes, clock adjustments, or synchronization failures.
Caution: Time synchronization events may be logged with different event IDs and descriptions depending on the Windows version and configuration, so it is important to consult the relevant documentation or seek expert advice if unsure about the event details.
Once you have opened Event Viewer, expand the “Windows Logs” folder and click on the “System” log. Look for any time-related errors that may indicate an issue with time synchronization, such as “The time service has not synchronized the system time for x seconds/minutes/hours” or “The time provider NtpClient is configured to acquire time from one or more time sources, however none of the sources are currently accessible”.
If you see any time-related errors, note the event ID and error message, as well as the date and time the error occurred. This information will be useful for troubleshooting the issue.
If you do not see any time-related errors, it does not necessarily mean that there are no issues with time synchronization. It is possible that the errors are being logged in a different log, or that there are no errors at all.
Step 3: Verify time synchronization with the Windows Time Service log
After checking the System log for time-related errors, you can also use the Windows Time Service (W32Time) log to verify time synchronization. The W32Time log records all time-related events, including the successful synchronization of time from an external time source.
To access the W32Time log, follow these steps:
- Open Event Viewer, as described in Step 1.
- Expand the “Applications and Services Logs” section in the left-hand pane.
- Expand the “Microsoft” folder.
- Expand the “Windows” folder.
- Expand the “W32Time” folder.
You should now see a list of W32Time log entries in the middle pane. Look for events with an Event ID of 35, which indicate successful time synchronization with an external time source. If you do not see any Event ID 35 entries, it is likely that time synchronization is not occurring properly.
If you do see Event ID 35 entries, you can further verify time synchronization by checking the “Time Provider” field in the Event Details. The Time Provider should be the name of the external time source from which the system is synchronizing time.
