ABSTRACT:
A method insures the NETBIOS names are not illegally used on a local area network. The NETBIOS protocols use a naming system that allows any station to claim a name or set of names that are not already in use. This potentially allows any user to "masquerade" as another user, or service machine, by claiming the name when the real user is not connected to the network. This method detects these attempted masquerades, disconnects the offending station from the network, and logs information about the attempt.
