The Special Poll Interval parameter is located in the registry at: A generally accepted polling period of once every hour, or 3600 seconds, is reasonable.
The default is 604800 seconds, or 7 days. This specifies the synchronization period in seconds.

To change the period at which Windows attempts to synchronize with the NTP reference, modify the parameter ‘Special Poll Interval’. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type The Type parameter is located in the registry at: This indicates synchronization to a NTP reference is required. To configure the time service to allow Windows to synchronize to an external time reference, modify the parameter ‘Type’. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\NtpServer The NTP server key is located in the registry at: The flag ‘Use as fall-back only’, indicates that the associated time reference should only be used as a fall-back reference in event og failure of other specified references. If left reset, the time service will select a poll interval based on the quality of the received samples. The special interval flag instructs the time service to poll the associated time reference at the period specified by the special poll interval, described below. A set of 4 flags are specified covering bits 0 to 3:īit 0: Special Interval, flag value 1 (0x01).īit 1: Use as fallback only, flag value 2 (0x02).īit 2: Symmetric Active, flag value 4 (0x04). The flags are specified after the DNS or IP address separated by a comma. Each time reference can optionally have a set of flags associated with it. Either DNS addresses or IP address can be specified. The Windows Time Service key ‘NTPServer’ specifies a space-delimited list of NTP time servers that can be used for synchronization purposes. There are a number of options available, including, the ability to set a time server, change the period at which synchronization occurs and also allow the Windows server to act as a NTP server to clients. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters For the Windows Time service, it’s associated options and parameters are stored at: Most application have an associated parameter list stored in the registry. The registry editor, regedit, can be used to modify options and settings stored in the registry. The registry is a database where Windows stores configuration settings and options. The Windows Time Service is configured by modifying registry settings. If any issues arise after changing any registry settings, the old settings can be re-established using the ‘Import’ menu option. Backing up is achieved by using the ‘Export’ menu option in the registry editor, Regedit.exe, application. We therefore recommend that before changing any settings, you make a backup the registry. Warning: Changing registry settings incorrectly can cause problems. modifying associated registry settings.This article provides information on how to: The service is installed by default in the service list, the executable file is called w32time.exe and is stored in the windows/system32 directory. The service continued in Server 2003, right up to the latest Windows Server 2008 operating systems. With the introduction of Windows 2000, Microsoft adopted a time synchronization service – Windows Time.
