Hi James, When you say "can't handle more than one DHCP server on the network", are you saying that the PICDEM.net board has its own DHCP server? I don't understand why that would be. I am assuming that your "home hub" is really a router and has a DHCP server. If so, that should be the only DHCP server on the network. It should be able to supply a configuration to your PICDEM.net board. I would check the settings on your router (which are likely accessible through the built-in web server). It may be that it is presently set up to issue only one IP address and that address is being used by your PC.
