The win7 Ultimate system windowstime service fails to start

. The Windows Time system service keeps date and time synchronized on all Windows XP-based and Windows 7 and Windows 8-based computers on the network. This service uses Network Time Protocol (NTP) to synchronize computer clocks to assign accurate clock values ​​or timestamps for network authentication and resource access requests. The implementation of NTP and the integration of time providers help Windows Time become a reliable, flexible time service for your business. For computers that are not joined to the domain, you can configure Windows Time xitongtiandi.com to synchronize the time with the external time source. If this service is turned off, the local computer's time settings will not be synchronized with the time service or externally configured time service in the Windows domain.
Repair:
1. Run, enter the command line, then type w32tm /register The correct response is: W32Time successfully registered.

Time server IP address and time synchronization method of China National Time Service Center:
Everyone knows that the time of win7 Ultimate system is maintained by a battery, and the accuracy is often poor. when. Automatic and regular synchronization of the local standard time can be achieved through some public network time server NTPserver published on the Internet.
Relying on the default server synchronization time of Windows7 or NIST, which is the default Windows/NIST system, there are always factors such as access congestion and large time delay (low synchronization accuracy). Now China's National Time Service Center has released a time server address. You can use the standard time of the Chinese people!
Use the time synchronization function that comes with the system
Take the win7 Ultimate system as an example, click on the bottom of the system tray. Time, click on the “Change Date and Time Settings” in the pop-up window, pop-up “Date and Time” dialog box, select “Internet Time” tab, click ““Change Settings” button to pop up & ldquo; Internet time setting & rdquo; dialog box, enter the IP address of the national time center server in the server address bar: 210.72.145.44, click the "immediately update" button, click "and confirm" button to exit, OK .
