Try the following.
Assuming you are behind the firewall and running unix.
1. nestat -an | grep
see what is echoing back to the screen.
If the sending and receiving system shows as up and you should see something like this.
tcp4 ESTABLISHED.
tcp.4 555.55.44.44 999.33.44.88 ESTABLISHED
anything else like wait or something, your TCP/IP packets are going thru.
try bouncing both sides at the same time and bring the sender first and then receiver.
2. Have your network folks check the firewall as well.
Hope this helps.
