Another, I assume unrelated, problem that we're seeing is that samba panics every time the nmbd server rejects a registration request. Go ahead and check out what the logs indicate, and if you have any advice, please tell me. I've already submitted this to samba-bugs because that's what they say to do for these errors. -----------NMB Log Level 3------------ *Initial registration:* wins_process_name_registration_request: Unique name registration for name DEFAULT<03> IP 134.10.25.169 add_name_to_subnet: Added netbios name DEFAULT<03> with first IP 134.10.25.169 ttl=518400 nb_flags= 0 to subnet WINS_SERVER_SUBNET *A refresh from a different IP, which Samba ignores:* wins_process_name_refresh_request: Name refresh for name DEFAULT<03> IP 134.10.25.46 wins_process_name_refresh_request: Name refresh for name DEFAULT<03> with IP 134.10.25.46 and is IP is not known to the name. *Another registration, a release, and a confirmation, all from the original IP:* wins_process_name_registration_request: Unique name registration for name DEFAULT<03> IP 134.10.25.169 wins_process_name_release_request: Unique name release for name DEFAULT<03> IP 134.10.25.169 add_name_to_subnet: Added netbios name DEFAULT<03> with first IP 134.10.25.169 ttl=518400 nb_flags= 0 to subnet WINS_SERVER_SUBNET *Lots of releases from that original IP:* wins_process_name_release_request: Unique name release for name DEFAULT<03> IP 134.10.25.169 wins_process_name_release_request: Unique name release for name 4AXG3<03> IP 134.10.25.169 wins_process_name_release_request: Unique name release for name 4AXG3<00> IP 134.10.25.169 wins_process_name_release_request: Group name release for name WORKGROUP<00> IP 134.10.25.169 *Another registration from that original IP:* wins_process_name_registration_request: Unique name registration for name DEFAULT<03> IP 134.10.25.169 add_name_to_subnet: Added netbios name DEFAULT<03> with first IP134.10.25.169 ttl=518400 nb_flags= 0 to subnet WINS_SERVER_SUBNET *A completely different IP tries to register, the NMB server rejects it* *and then crashes.
