My guess is that you've misspelled the name of the hostgroup 'allhosts'
when defining it on line 47 in /usr/local/nagios/etc/objects/windows.cfg,
or that the hostgroup "allhosts" indeed has no members, so that Nagios
fails to add it properly and therefore cannot find it when you're using
it to define one or more services.

Because you haven't gotten everything correct. Sorry, but the two are mutually
exclusive, so either you have got it all right and won't see the error, or you
somehow fscked up and you see the error.
