Java RMI application on two different machines - ConnectException

[John Went]

Hello. Long story short I am trying to run a client server RMI application on two different machines running Windows, but I have some trouble.

A simplified code of the server is:

System.setProperty("java.rmi.server.hostname", "192.168.x.x");  
Registry reg = LocateRegistry.createRegistry(1099);  
RemoteFoo foo = new RemoteFoo();        
reg.rebind("Foo", foo);  

And the Client:

reg = LocateRegistry.getRegistry("192.168.x.x", 1099);
RemoteFooInterface foo = (RemoteFooInterface) reg.lookup("Foo");

The exception I get is: "ConnectException: Connection refused to host: 192.168.1.100; nested exception is: Connection timed out: connect".
I know this question has been asked a million times and I found out that I have to change the properties of the server and that is why I added the System.setProperty("java.rmi.server.hostname", "192.168.x.x"); line but the error remains. For the IP addres I am using the one returned from ipconfig.

I will be very thankful if someone could suggest what I can change.

Welcome to the Ranch.

Have you tried pinging from the client machine to the server to make sure there is a route to IP address 192.168.1.100 - it may be being blocked by a firewall.

Yes, it was because of the firewall. Thank you for the suggestion.
