Hi Vincent
If you are using a hardware router or non-xp internet sharing service you
will not be able to use Video and Voice in Messenger. Messenger uses a
technology called Universal Plug (
http://www.upnp.org/) and Play (UPnP).
Currently the only internet sharing (NAT) software that is UPnP compatible
is the built in Internet Sharing included with Windows XP. Hardware and
software vendors are building UPnP support into their products and should be
available soon. For firewalls, the built-in Windows XP Internet Connection
Firewall opens the ports for video/voice automatically, but other firewalls
do allow video/voice to pass -- by opening ports 5004-65535.
If this doesnt solve your problem feel free to subscribe to the following
main Windows Messenger newsgroup for more luck. -->
microsoft.public.windowsxp.messenger
Hope this helps,
