Win2k Server does install and listen on snmpv1, public by default (at
least our CDs of it do).  I have no idea how or why it was enabled,
but a little quick scanning turned up some scary results.

Similarly, we disable snmpdx on all our Sun hardware.  Several patches
from Sun re-enable this service.  They don't restart it, they just
replace the /etc/rc3.d/S76snmpdx init script.  So the next time the
system boots, you get a happy surprise.
