wins; lost packets

Hello All,

My computer tries to register in WINS:

nmbd_incomingrequests.c:

/****************************************************************************
Process a name registration request on a broadcast subnet.
**************************************************************************/
void process_name_registration_request(struct subnet_record *subrec,
                                       struct packet_struct *p)
--------------------------------------------------------------

does nothing with this packet:(

namerec = find_name_on_subnet(subrec, question, FIND_ANY_NAME);

So, namerec=NULL and function simply ends. No error, no
add_name_to_subnet => packet lost, registration fails.I think, function
process_name_registration_request should be similar to
wins_process_name_registration_request?


Best wishes,
