A. All versions of Windows 2000 and later can serve as an NTP server. Other machines on the network can then use the NTP server to synchronize their time. To enable an NTP server, perform the following steps:

  1. Start a registry editor (e.g., regedit.exe).
  2. Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters registry subkey.
  3. From the Edit menu, select New, DWORD Value.
  4. Enter the name LocalNTP, then press Enter.
  5. Double-click the new value, set it to 1 to enable or 0 to disable, then click OK.
  6. Restart the computer for the change to take effect.

To configure other network computers to use the new NTP server, you must set their NtpServer registry value, which is located under the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parametersregistry subkey, to point to the NTP server. For more information about configuring NTP settings, see the FAQ titled "How can I configure the time service in Windows 2000?".
