I totally agree

NetBios is a very bad protocal
and will get you into trouble.....
I personally am a firm belever of using
Linksys Routers and non-routable IP addresses
for internal networks.....

Big mistake I see that the NetBoui Protocal is no longer
pushed or spported by MS in XP and you cannot choose which
way to bind file sharing..

I will say XP has improved things over 98/ME
only problem there I see is that the built-in firewall
in XP is that it is not turn on by default.
