Hello world, I tried the Basic Client-Server example from 
Builder 6.0, from Indy folder (Who is Indy? it's sound like a 
person name...), When I tested it on a single computer it looks 
like it's working, first I run the 'Server' application, then I 
run the 'Client' application, clicked on the button, and I got 
the "Hollo" line message in the ListBox, But if I run 
the 'Server' application on one PC, and then I run the 'Client' 
application on another computer that is connected to the firt 
one by a local networking, then when I click on the button I 
get an error message saying - "Socket Error # 10061 Connection 
refused"

Can someone please explain to me this example and what should I 
do in order to make 2 computers talk with each other using this 
Client-Server applications?

Thanks very much!

Ori.
