It'd be nicer ifnmbd log messages like this contained timestamps, so they could be correlated with other events. This one is a dialup client machine disappearing, but I wish I knew when! Packet send failed to 192.52.153.119(137) ERRNO=Host is down retransmit_or_expire_response_records: Failed to resend packet id 9291 to IP 192.52.153.119 on subnet WINS_SERVER_SUBNET I hope that error caused the client to be deregistered! Looks like it did - the IP address isn't present in the wins.dat file. (This nmbd, 1.9.18p4, is our wins server.)
