The short answer is .... well, it depends. In h node the default search
order for name resolution is:
1. NetBIOS name cache
2. WINS server
3. B-node broadcast
4. LMHOSTS file
5. HOSTS file
6. DNS server
A Windows computer assumes you are seeking to resolve a NetBIOS name unless
you use a winsock based program such as ping or http. In that case, the
search order becomes, cache, hosts file, DNS server, and yup - lmhosts file.
