Explanations

„The NTP Server function is enabled in accordance with the following procedure with Windows 2000.

1.Start up the command prompt (DOS screen) and enter the following command.

net time /setsntp: Server IP address

Example: net time /setsntp: 192.168.0.1

2.Open the [Control Panel] [Administration Tools]

[Services].

3.Double-click on [Windows Time], set [Start-up Type] to [Automatic], and then click on the [Start] button.

4.Set the following registry value to [1] (the default is [0].) HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\W32Time\parameters\LocalNTP

It is very risky to amend the registry. It is recommended that a back-up of the registry is taken prior to commencing the editing for safety purposes.

JCV cannot be held responsible for any problems that arise from this.

5.Reboot Windows Time Service (= Stop Start)

This is performed by opening the Windows Time Service property from the [Service] screen on [Administration Tools].
