I'm currently trying to fix apps that fail doing the following (which seems to be a popular way among game developers), in pseudo-code. hostname = gethostname(); hostent = gethostbyname(hostname); sockaddr->sin_addr = hostent->addr; sock = socket(); bind(sock, sockaddr); Which, as Christoph noted, cause windows apps to bind to loopback addresses, breaking the networking. This only started to happen recently as recently Linux distros started mapping the machine's hostname to a loopback address. I don't think Wine ever used the registry for anything like that.
