I get the following exception:
"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond ...".
State of play:
The client and server are written in C #.
3 remote computers, lets call A (Seven Ultimate), B (Seven Family) & C (XP Pro).
I did the port translation NAT on the PC 3.
A and B have a static IP configured via DHCP (I do not know if it's really useful).
Client / server work perfectly well in local on the 3 PC, so I do not think it is a programming problem.
Server A, Client B does not work (Exception).
Client A, Server B works.
Server A, Client C works.
Client A, Server C does not work (Exception).
I ping A and B without any problem, and (for whatever reason) not C (but I do not have access to this machine, this is a friend's computer), I do not know if this information may be useful.
I can not understand at all why the configurations server A / Client B and Client A / Server C does not work while the opposite yes...
So, if someone has an idea don't hesitate ...
Thank you in advance for your help.
