3rd request for some wonderful persons help!

Question

I'm trying to connect across a network with RMI and I get the error:
"Connection refused to host 138.79.115.36; nexted exception is: java.net.ConnectException: Connection refused: connect."
138.79.115.36 is the machine my client is on
138.79.115.30 is the server machine
I have one jar file which I've unzipped on both machines. It contains the following folder structures
../kye/db/
../kye/clientGUI
../examples/classServer
the db folder has all the files for running the RMI server
the clientGUI has all the client GUI files.
the examples/classServer is the webserver that it is suggested to download in the RMI tutorial
I tried to follow the sun tutorial but I only have one jar file so it's a bit modified. And I know somethings are unecesarily duplicated. Maybe this is part of the problem. Not sure.
Everything is unzipped in d:\public (which is shared) on the server and I use the following commands to start everything running.
Start the webserver
d:\public>start java examples.classServer.ClassFileServer 2222 /public
Start the server
start java -Djava.rmi.server.codebase=http://138.79.115.30:2222/ kye.db.DataServerGUI
Then on the client machine
java kye.clientGUI.ApplicationRunner
When the client opens it asks for the servers ip address, I enter it and when connecting get the above error. I have a policy file which is specified in both the client and the server. It contains this:
grant
permission java.security.AllPermission;
permission java.net.SocketPermission
"*:1024-65535", "connect, resolve";
What do I have to change or fix to get this running?
I'm happy to send out copies of the .jar file to anyone who needs more information.
I appreciate any help and I'm pretty desperate
Thanks

Thanks John,
It does seem a strange message. But the ip addressses are definitely correct that I'm entering. I wondered why the client would say that the client refused connection.
Here is the code for making the client connection:
public ServerClient(String ipAddress)throws DatabaseException{
try{
System.setProperty("java.security.policy", "access.policy");
if (System.getSecurityManager() == null) {
System.setSecurityManager(new RMISecurityManager());
db = (DataClient)Naming.lookup(ipAddress + "/kyeData");
}catch(RemoteException re){
throw new DatabaseException(re.getMessage());
}catch(Exception e){
throw new DatabaseException(e.getMessage());
Here is the code that registers the RemoteServer:
try{
System.setProperty("java.security.policy", "access.policy");
if (System.getSecurityManager() == null) {
System.setSecurityManager(new RMISecurityManager());
//ClassFileServer cfs = new ClassFileServer(2222, "suncertify.jar");
server = new DataRemoteImpl(databaseName.getText());
output.append(InetAddress.getLocalHost().toString() + "\n\n");
//start up the registry and add our object
java.rmi.registry.LocateRegistry.createRegistry(1099);
Naming.rebind("rmi://" + InetAddress.getLocalHost().toString() + "/kyeData", server);
//check to make sure it is bound????
String bindings[] = Naming.list("");
for(int a=0; a<bindings.length; a++)
output.append(bindings[a] + "\n");
Is there anything you can see that's wrong or in the wrong order? I start the registry from within the RemoteServer. I've commented out the webserver that I was trying to use to locate files. I'm not sure if that was working.
Any more ideas? I've tried it on different networks in the office, to make sure that none of our security systems were interfering and the same things occurred on all the different machines.
