proto.h : Removed broadcast and recurse parameters in the
queue_netbios_pkt_wins() call - they are not needed as they
should always be 'false' and 'true' respectively.
Also fixed a bug with secure name registration (WINS
server code).
server.c: Finally fixed problem with error 267 being
returned to Win95. It is needed by NT. This is a horrid
fix and I would appreciate a better one :-).
