Answer 1

In descending order of probability where it comes from:
NETBIOS, WINS, DNS, hosts

Answer 2

In policies, explicitly prohibit desktops from trying to become a master browser ... well, it's also possible for them to turn off the use of NetBIOS over TCP / IP

Answer 3

These are netbios names. Each computer with Windows automatically distributes its name and address in the local area. Each Windows by default accepts these names and shows them as if with dns.
NetBIOS

Answer 4

Any sysadmin knows that, in general, name-to-IP mapping is the job of DNS.
