Has anyone here used DirectPlay? I'm making some DirectPlay components for my own use and I found this interesting bit. If you enumerate hosts, you can optionally specify a host to search. Using '127.0.0.1' or 'localhost' will only search the local machine, for example. If you do not specify a host, then it does a broadcast over the LAN which should rightly include the local machine. But here's the catch. If you do not have a network cable plugged in, the search will not find the local server. Plug the network cable in to a hub and it will find the local server.

Just thought I'd share.
