I found this in a few different places around the 'net - hopefully it's helpful:

Activate NetMeeting

Using NetMeeting, you can participate in virtual meetings, work in shared applications, and share data over the Internet or your company intranet. NetMeeting is actually already installed after you perform a full install of Windows XP, but it won't appear on the Start menu until it's activated.

  • Click Start, then Run, and enter Conf.
  • Click OK.
  • In the NetMeeting Wizard, supply the necessary information, and then select the Put a shortcut to NetMeeting on my desktop (or on my Quick Launch bar) check box.

NetMeeting should start and is now listed in the most frequently used programs list on the Start menu.

Thanks for the information,it will help me keep in touch with my girlfriend :D
