Disconnect all "services" from a specific network card

Hello all,

For the purpose of proxying / sectioning off an untrusted device I would
like to "disconect" *one* of my installed ethernet cards from all (default)
services (especially IPC) running on my computer (XP Pro).

At the same time I would ofcourse still like to be able to have userland
programs communicate thru (open ports on) that ethernet card.

Is this possible, and if so how ?

Regards,
Rudy Wieser

No. Because there's no standard method to make other process' to stop
listening to a network port.

JJ,

There is ! Just shut down the service(s). :-) (and yes, on an
experimental setup thats exactly what I did).

And I'm not asking for a "kick a process off" method (which, by the way, I
have seen described somewhere) as it would *at best* be prone to problems,
both in the "will it or won't it close the port" department, as well as in
the attack window that will exist between the time a process (system
service) opens a port, and the "kick it off" moment.

I'm inquiring to a method by which I can *tell the OS* to tell the services
not to make the connection.

Using a 'puter to proxy (monitor and/or filter) network traffic is not that
uncommon. Must I assume that Windows is incapable of doing anything of
that kind ?
