This is used when sending a name query to a machine running a WINS server and the user wishes to query the names in the WINS server. If this bit is unset the normal (broadcast responding) NetBIOS processing code on a machine is used instead. See RFC1001, RFC1002 for details.

The reason for this option is a bug in Windows 95 where it ignores the source port of the requesting packet and only replies to UDP port 137.
