Network Time Protocol enhancements


 / Published in: Windows Registry
 

Three objectives are accomplished here:

  1. Allow the machine to act as an NTP server on the local network, so you have the option to synchronize all other machines from the one. Handy if all machines must be closely sychronized.

  2. Reduce the NTP polling interval to four hours. The default setting is a week, which is plenty of time to become unsynchronized.

  3. Add more NTP servers and change the default. Most computers are synchronizing with time.windows.com; this massive load causes delays and means that your computer's clock may be a few seconds behind.

  1. Windows Registry Editor Version 5.00
  2.  
  3. ;Allow machine to act as an NTP server on the local network
  4. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters]
  5. "LocalNTP"=dword:00000001
  6.  
  7. ;Reduce NTP polling interval to 4 hours
  8. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient]
  9. "SpecialPollInterval"=dword:00003840
  10.  
  11. ;Add more NTP servers to ease load on primary
  12. [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers]
  13. @="7"
