That's a best practice for any public-facing NIC, but unfortunately, it has
nothing to do with name broadcasts.
You have to set the regvalue to gain quietness from those.

The other thing you could do - and which I usually do for external-facing
interfaces that will only be servicing specific TCP traffic (80, 443, 25, etc.)
- is flip to the WINS tab on the TCP/IP Properties Sheet for the interface and
select the option "Disable NetBIOS over TCP/IP" in the NetBIOS setting box.

What you see has nothing whatsoever to do with those bindings.
HKLM\System\CurrentControlSet\Services\NetBT\Parameters
Name: NodeType
Type: DWORD
Value: 2
If it doesn't exist, create it and give it a value of 2.
Reboot the server.
All gone bye-bye; cya...
This happens because Windows operates as a M- or H-node by default (depends on
the installation process and network detection logic). By adding this value,
you change it to a peer-node, which will not use NB name broadcasts.
Name resolution failures return much more quickly (don't have to wait for bcst
cycles) and ISA doesn't have to waste time blocking and logging these packets.

Subject: [isalist] Netbois Name Requests from my external Network Interface

Hello,
I have a continuous barrage of netbios name requests coming from my external
network interface on my ISA server. These are being denied but I'm not sure why
they are occurring in the first place. The interface does not have either the
Client For Microsoft Networks or File and Printer Sharing Enabled. Is it normal
for this traffic to occur from the external Network Interface?
Thanks Bill
