NBName decodes and displays all NetBIOS name packets it receives on UDP port 137. Using the /DENY * command line option it will respond negatively to all NetBIOS name registration packets it receives. Using the /CONFLICT command line option it will send a name release request for each name that is not already in conflict to machines it receives an adapter status response from. The /FINDALL command line option causes a wildcard name query request to be broadcast at startup and each machine that responds to the name query is sent an adapter status request. The /ASTAT command line option causes an adapter status request to be sent to the specified IP address, which doesn't have to be on your local network. Using /FINDALL /CONFLICT /DENY * will disable your entire local NetBIOS network and prevent machines from rejoining it.
