Re: Two NICS - Windows XP - I don't want any traffic between them

OK, there is a box for a phone system. You plug it into your computer. The
computer then takes incoming messages and routes them to your e-mail. The
e-mail goes through the internet on the second adapter - the 1st going to
the phone box. The phone program works fine up until the point I plug in
the network adapter on the second nic. The phone box is not connected to
anything else - e.g. network, internet, other pcs.
