Configure the eSight Server as the NTP Client (Windows)

Prerequisites

To reduce the impact caused by the time difference between the Windows system and the NTP server, modify the time of the Windows system based on that of the NTP server to ensure that the time difference is less than 1000s.

Procedure

1. Choose Start > Run. In the Run window, input cmd and press Enter.
2. In the DOS window that is displayed, input gpedit.msc and press Enter.
3. On the Local Group Policy Editor page that is displayed, choose Computer Configuration > Administrator Templates > System > Windows Time Service > Time Providers.
4. On the Time Providers page, double-click Enable Windows NTP Client. On the Enable Windows NTP Client page, select Enabled. Then, click OK.
5. On the Time Providers page, double-click Configure Windows NTP Client. On the Configure Windows NTP Client page, configure the NTP client information.
   • Select Enabled.
   • Set NTPServer to the IP address or domain name of the NTP server.
   • If it is set to the IP address, the format should be IP address of the NTP server,0x1, for example, 10.137.77.188,0x1.
   • If it is set to the domain name, the format should be Domain name,0x1, for example, time.windows.com,0x1.
   • Set Type to NTP.
   • Retain the default values for other configuration items.

6. Configure the Windows service to automatically start upon the operating system startup.
   1. In the DOS window, enter services.msc. On the Services page, double-click Windows Time. In the dialog box that is displayed, set Startup Type to Automatic.

      Then, check Startup Type. If the startup type of Windows Time is Automatic (Trigger Start), run the following command to change the startup type to auto-start in the DOS window:

      sc triggerinfo w32time delete

   2. On the Services page, double-click Remote Procedure Call Locator. In the dialog box that is displayed, set Startup Type to Automatic.

7. Set the maximum time correction.
   1. In the DOS window, input regedit to open the registry editor.
   2. Choose HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > W32Time > Config.
   3. In the right pane of the Registry Editor page, double-click MaxPosPhaseCorrection. In the dialog box that is displayed, set Base to Decimal and Value data to 1000. Then, click OK.
   4. In the right pane of the Registry Editor page, double-click MaxNegPhaseCorrection. In the dialog box that is displayed, set Base to Decimal and Value data to 1000. Then, click OK.

8. Restart the Windows Server.
