I agree with all that you said. My point was that no matter WHAT lengths
you go to, if you aren't also keeping your systems patched for known
vulnerabilities, you aren't making every reasonable attempt to secure
your network.

That's why you should enable the Windows firewall on all desktops and
enable IPSEC pass-through from a specific domain group and do the same
on all servers but allow domain computers access. This isolates the
desktops so that they can only be infected by trusted systems (if
trusted they shouldn't be able to be infected). And isolates your
servers to all but domain member machines. When you do this, if a rogue
system enters your network, they may have the worm, but the cannot
infect anything (except other rouge systems).
