You've commented out your service definitions for these hosts, but still
have host definitions left in. These hosts are being checked with a
check_command (most probably check-host-alive in a default Nagios), and
since the machines are offline, they show up in Nagios as down.

Go to your $NAGIOSHOME/etc directory and do a "grep -R machinename *" where
machinename is the host you want to remove. It'll show you all the places
where you mention that host, which will let you know which file you still
need to edit. Then do the verify+reload dance again :-)
