When a gethostbyaddr() uses a NETBIOS Node Status Query to return the
Machine Name of a device, it will return the first instance of the machine
name that is registered as Unique [00h]. The order of the Unique <00> name
registered can be viewed by running NBTSTAT -N at a command prompt.
CAUSE
Some services, other than the Workstation, that Register as Unique with the
[00h] entry, will show up in the NETBIOS Node Status Query response as well
as the Machine Name. These names can be returned by a gethostbyaddr() and
can incorrectly identify the computer if they are listed first in the
response above the Workstation Name entry.
