Firewall administrators frequently see larger numbers of incoming packets to port 137. This is because of Windows servers that use NetBIOS (as well as DNS) to resolve IP addresses to names using the gethostbyaddr() function. As users behind the firewalls visit Windows-based Web sites, those servers frequently respond with NetBIOS lookups. | |
