Modify the Internet Time Synchronization Servers (Windows XP)

Windows XP includes a new feature that allows it to synchronize the system clock from atomic clocks available on the Internet. This setting lets you add new servers and change the default server used.

This tweak can be easily applied using WinGuides Tweak Manager.

Open your registry and find the key below.

To add a new NTP server simply create a new string value and name it the next sequential number (e.g. '3'). Set the data of the new value to equal the hostname or IP address of the server.

You can also change the default server by setting the value of "(Default)" to the entry number of the required server.

Changes will take effect on the next use of the Internet time feature.
