WinPcap does not show in the list of protocols of the NIC. Do the NICs get listed in Wireshark?

Have a nice day

The installer definitely said it was installing it but I don't see it anywhere. Maybe I'll re-install and see what happens.

Ok, just noticed that on new system, after installing wireshark, there are
no capture protocols on either nic. Guess that's a lead.

MS client gets disabled if you disable TCP/IP. QoS can be disabled as
well.
The network monitors can be left on.

Because it is a netbios based service, which rides on tcp/ip?

You are disabling TCP/IP on the public NIC. The LAN NIC will have its
own
IP
address, the public one will not. As far as "safely connect" is
concerned,
it depends on what you mean by "safely".

Yes, the server has two NICs. I have one connected on the LAN side for
server admin, etc, the other is connected to a hub which has the WAN
connections coming into it, just before the firewall. I want to see what
hits us before the firewall does anything with it. It helps a lot when
trying to figure out various problems.

What do I mean by safely? Meaning that public cannot gain access to the
server in some way. I mean, the setup bypasses the firewall so sure
don't
want someone being able to gain access into the lan somehow.
