assign ip numbers to your internal nics in the range 192.168.x.x
calm the paranoia Brian, if ms actually wanted to spy on you do you think they couldnt use netbeui to do so? there own code? lol.
eg
.................computer1.........................computer2
internet<--->dhcp dialup.......................ethercard set to
.................ether card (192.168.0.1)<------->ip=192.168.0.2
.................gateway blank...................gateway=192.168.0.1
.................firewall on
if you really want to use the slow pig that is netbeui then you can find it on the xp disk in valueadd\msft\net. Searched everywhere huh.
