    Agreed.  I'm not sure, however, that David's idea doesn't have an
    affect on stability.  Not the stability of a single server but on an
    environment consisting of many servers.  I'm not Windows wizard, but
    I'll accept from everything I've already read in this thread that
    rebasing on a single system will not have a negative impact on it.
    However I question how will it scale to several tens of servers, which
    is my problem?  Is there an easy way to automate it such that it is
    done after patch application?  Considering how difficult and/or
    expensive, take your pick, it is to apply patches in an automated
    fashion on Windows systems I suspect not.  Moreover, I gather that for
    the solution to be effective, each system should be rebased
    differently requiring even more planning to get it right even if
    automation were easy.  This should not be taken as an indictment of
    the idea, just asking that when implementing security solutions on
    individual machines, the keepers of security should consider the
    issues of scale that we sysadmins have to deal with.
