Actually, there are valid reasons for these recommendations.  IIRC, two of
the major ones were "eliminate blank or weak administrator passwords" and
"stay up-to-date on security patches".  These are also mentioned in the
"SANS/FBI Top 20 List", which can be viewed at


SQLSnake and Nimda/CRII are good examples of what can happen when you don't
follow these.

Running current A/V software and making sure your internal servers are
behind a firewall are also considered generally good things to do.
Disabling the GUEST account is a Windows-specific thing, but it is also a
very good thing to do (in fact, renaming the account, setting the password
to a randomized strong string (alpha, numeric, special and non-printable
characters), and setting the flag to prevent it from logging on, is probably
the best thing you can do to it.
