Changing the Windows NTP Root Dispersion Settings

1. Access the registry settings associated with the root dispersion on the Windows NTP server, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config.
2. Set AnnounceFlags to either of the following values:
   • 0x05 = 0x01 (Always time server) and 0x04 (Always reliable time server)
   • 0x06 = 0x02 (Automatic time server) and 0x04 (Always reliable time server)

     ---

     Note -  Do not use 0x08 (Automatic reliable time server) because its dispersion starts at a high value and gradually decreases to one second or lower.

3. Set LocalClockDispersion to 0.
