When the NBSS dissector sees error code 0x81 in a Negative session response
packet, it calls the error "Not listening for called name". See the table in
epan/dissectors/packet-nbt.c:

static const value_string nbss_error_codes[] = {
    { 0x80, "Not listening on called name" },
    { 0x81, "Not listening for called name" },  <=== HERE
    { 0x82, "Called name not present" },
    { 0x83, "Called name present, but insufficient resources" },
    { 0x8F, "Unspecified error" },
    { 0x0,  NULL }
};

This is wrong (and confusing). 0x81 should be "Not listening for calling
name"--"calling" not "called". The error is supposed to indicate the server is
not willing to talk to a client having a certain name. In fact, Samba returns
it when the client is denied access by hosts allow/deny.

See:
