True, however WINS will not function without NETBIOS. If you don't
need this, then there is no need for netbios. Also, anything which
relies on WINS won't work.

Apples and oranges; netbios is a session level protocol. TCP/IP and
Netbeui are both lower level. FWIW, TCP/IP is pretty insecure unless
you are using ipsec or some such. Also, NetBIOS is as secure (for
internal) as the TCP/IP implementation it rides on.

Definitely block it all at the perimeter, but for internal purposes, I
like NetBIOS, esp. in smaller installations.
