Mike, I tried but it doesn't make any difference. I still get the same error. Is there any known software conflicts?

I was running Sun's sample RMI code and it still gives me a problem. I looked up many helps on-line and I think I did everything correctly but I am still facing problem. Please help.
1. First everthing is under D:\TIEJ1.1\Code\rmiex and the service name is given as following in engine\
String name = "//localhost/Compute";
2. Then compiled this code.
set classpath=D:\TIEJ1.1\Code\rmiex
javac engine\
rmic -d . engine.ComputeEngine
3. So there are three classes in engine directory, ComputeEngine.class, ComputeEngine_Stub.class and ComputeEngine_Skel.class.
4. java2.policy file is set like this in D:\TIEJ1.1\Code\rmiex.
grant codebase "file://D:/TIEJ1.1/Code/rmiex/*" {
permission "*:1024-",
permission "*:80",
5. Run the server code.
set classpath=D:\TIEJ1.1\Code\rmiex
java -Djava.rmi.server.codebase=file// :/TIEJ1.1/Code/rmiex
6. Now i get SocketPermission error.
ComputeEngine exception: access denied ( connect,resolve) access denied ( connect,resolve)

Most of the people who saw the same error seemed to solve the problem by fixing policy file but I cannot do that. I don't know why. The only thing that I could think of was Norton firewall. So I tried the same thing turning on and off Norton but it doesn't make any difference. Does anyone have a clue? Please help me on this.
