sed can be awkward when working with more than one line at a time.
Can you use perl?
$ perl -pe 'BEGIN{undef $/};s/server 10.33.45.3\nserver ldap.example.com\nserver orion/# server 10.33.45.3\n# server ldap.example.com\n# server orion\n\nserver fire.example.com\nserver earth.example.com\nserver space.example.com\n/s' <test.conf
(That's meant to be all on one line.)
