Connection refused

What connection, exactly, do you show as "established" with netstat -an? 
It can't really be the one you are talking about, because that never 
connected.

In any case, you would want to look for LISTENING rather than 
ESTABLISHED in the output for netstat -an. The local address on the left 
should say something like 0.0.0.0:xxxx (where xxxx is the port number). 
If it says 127.0.0.1 then NSClient++ is not listening on the Ethernet port.

If you don't see an entry that listens on the correct port, then 
double-check that NSClient++ is running.

If you do see an entry to listen on the correct port, try running nestat 
-anb . This will tell you which program is actually doing the listening. 
If it isn't NSClient++, you found your culprit. That's not likely, though.

If netstat -anb shows NSClient++ as listening correctly, you almost 
certainly have a firewall issue.
