all UDP/138 packets have a source and destination netbios name in the
header. nmbd checks to see that the destination name is a local name
before looking at the packet.

In this case the destination name is the domain name (with 1C type??),
so only machines in that domain will answer.

PS: we once had a bug in nmbd where we forgot to check this, and it
caused havoc on multi-workgroup networks!
