Run telnet as follows from your Windows PC: telnet 192.168.0.2 1099 The last line of the response should contain the text UnicastRef2 followed by an IP address. Which IP address shows? Here is my last line when I telnet to my Fedora Core 5 system that is running JBoss: UnicastRef2192.59.193.104 What are the contents of your /etc/hosts file on the server? Do you have a line that has the IP address of the server? In my /etc/hosts files I have the following line: 192.59.193.104 usmv-johnsop1l If I recall correctly (it has been many months since I worked around a similar issue), without this line the telnet response has 127.0.01 as the IP address and this tends to confuse clients.
