I would try and see if someone on his local network can RDP
to his machine. You can use telnet to test whether tcp/3389 is open and
accepting connections (in a cmd window, type "telnet <ip
addr> 3389"). You will not get any human-readable feedback, but if
the command window stays open, you will know that the telnet session
connected.
More than likely, unless you are going through a VPN tunnel
or on a totally private (and somewhat open) network, your connection to his
machine would not be allowed by his company's firewall.
I am working with a user in Brasil who is the host
for a Remote Desktop Connection. He is running XP Pro. I am in NJ and am running
Win2000 pro. I am the client and I try to connect and it always fails. I had him
run ethereal on his PC during a test, and I expected him to see packets arrive
on port 3389, but nothing showed. What should I try next?
