At work we have a Win2000 domain server. I was wanting to setup a similar server at home to play with. Can I set it up with a fake domain name or do I need to shell out $30 or so and register a legitimate domain name to use on it? I am not really interested in setting up anything that will be web accesible from the outside right now. For now I just have it set up on a workgroup until I get this figured out on how to set it up on a domain. I should mention that at home I have 4 pc's networked to a router to share a cable modem, so I need to make sure that I don't create something that will interfere with real domain controlers. Thanks in advance for any help.
