If all the ISP's would implement solid in-addr.arpa reverse mappings, this would go away. Microsoft's DNS resolver has been extended, when DNS lookups fail, to do a reverse NETBIOS query against the target machine so it can use its name when displaying stuff via NBTSTAT, etc. It was designed this way, before the Internet became popular. Before we all rant at MS, I suggest we all read RFC's 1001 and 1002 and UNDERSTAND NetBIOS over IP, before we blame ALL the worlds ills on MS. Last I knew, they weren't written by MS.
