How to start java Server on Vista?

Question

Hello, i have already done some client - server programming and it worked too, but now i have got windows Vista and when i start the server, i can only connent to it from the computers that are connected to the same router, i am not sure where the problem is because all worked fine on windows XP, maybe im just using wrong port...
now i made a simple program,
package server;
import java.io.IOException;
import java.net.InetAddress;
import java.net.ServerSocket;
public class Test {
     public static void main(String[] args) {
          ServerSocket s = null;
          try {
               s = new ServerSocket(80, 50, InetAddress.getByName(InetAddress.getLocalHost().getHostName()));
               System.out.println(s.getInetAddress());
               s.accept();
          } catch (IOException e1) {
               e1.printStackTrace();
          finally {
               try {
                    s.close();
               } catch (IOException e) {
                    e.printStackTrace();
               catch(Exception e) {
                    e.printStackTrace();
          System.out.println("Finished");
}it does nothing, but prints "Finished" when someone connects,
it works, for example when i open intenet explorer and write "http://xxx.xxx.xxx.xxx" where xxx is my ip address. the program finishes, but when i try it from another computer which is not connected to the same router, then nothing happens
Thanks for help

I would check your windows firewall and your router settings. There is nothing in Java I know of which will do this.
