granted alot of companies and most gov and edu sites seem to not know how
to prevent a system from joinging the network without first being audited
to ensure it complies with the sites security poicy.  And for those
organizations, this posting by Paul rings true.  Those sites that have
stringent security policies and a means of enforcement of those policies
in place, do not face these problems, especially each and every time a new
sploit comes out.

Certainly worked for the groups I was associated with at NRTLE a few years
back, and their being spread globally, due to many acquisitions, as well
as having a variety of OS's to contend with, certainly had the numbers of
users and systems that seems to make many admins shudder at trying to
manage.  If the tools did not exist to do what we needed to do, we ended
up building our own.  We do much the same at the present location I work
in.  Though I have to admit, maintaining M$ is someone elses headache here
and was at Nortel.  But, some folks seem to handle it better then others.

Thanks,
