rmiregistry on Windows NT

Hi everyone,

I have a demo sample of the RMI code from Java Network Programming from O'Reilly.
A sample of the code follows.
Basically when I start the rmiregistry on my HP-UX box and then I start the
"java HelloImpl", it gives the message Server Ready and I'm able to run my
HelloClient in my client machine.

My problem is that when I start the rmiregistry and the HelloImpl on my NT
box, I don't get any message "Server ready" and my HelloClient fails with the
following message: "java.rmi.NotBoundException: hello"

How can I make it work with Windows NT?

Thanks

Jonny
