Answer: Whether you are using a dial-up connection or are connected to the Internet with a DSL or cable modem, you can configure ICS in Windows XP to synchronize your computer with an Internet time server by following these steps:

  1. Click Start, Connect to, Show all connections.
  2. Right-click the network connection and select Properties.
  3. Click Settings on the Advanced tab.
  4. Click Add and type Internet Time Service in the description box.
  5. Type 127.0.0.1 for IP address and type 123 for both external and internal port numbers. Make sure the TCP radio button is selected.
  6. Click OK three times to close all dialog boxes.
  7. If you are already connected to the Internet you'll need to disconnect and reconnect for the settings to take place.
  8. Now you can double-click the clock on the taskbar, click on the Internet Time tab, and select Update Now to synchronize your clock.

Note that if you aren't using the firewall, then you can simply use step #8 to synchronize your computer clock.
