Whatever I do, I am unable to setup a remote desktop connection over the
internet between two winXP computers. One is connected through ADSL of
hccnet.nl the other through wanadoo.nl. I begin to suspect that wanadoo is
blocking port 3389 irrespective of all my efforts to have this port open in
firewalls and have it forwarded by routers. How can I test that this the case?
 
Have you called "wanadoo" customer support?

Otherwise, on the PC that uses wanadoo as the ISP go to the
http://www.canyouseeme.org and see if the test passes. This presumes you
have port forwarding setup correctly on any firewall/NAT/router that is
between the PC and the ISP.
