Thank you for your reply.
The RDC is enabled.
The PC is behind the Windows XP firewall, and the problem is still
here when I desactivate the firewall.
I don't use a router (I desactivated on my modem), and I enter the
public IP of my home PC.
I have a direct DSL connection.
I'm calling the right ip, and I can ping it.
I'll look at the url you sent.
