Function
This command adds a 16-character name to the table of names. Group names allow
a single node to communicate with many nodes. The name added cannot be added
by anyone else on the network as a unique name but can be added by anyone as a
group name.

When the NETBIOS processes this command, it sends a broadcast request on the
network. If no unique name replies, the name is added. The command returns the
number of your name in the NCB_NUM field. This number is used in datagram
support and for Receive Any commands.
