    Wonder if Rouland would like to respond to that and his 100% certainty
    or if this was factored into the 'research' that lead to this
    And while we're on the topic of ISS and their "brief" (notice the
    legalise is longer than the content posted [1]) of the Slammer worm, I
    wonder why ISS then recommends using ISS Realsecure and ISS Scanner to
    help mitigate the worm. Checking SQLSecurityForum, we see that both
    products include SQL Server/MSDE that is vulnerable to same thing they
    are trying to protect against. Hope we see some advisories on these
    products soon.
