Hi Andrew, wheater the NRPE daemon is running or not has nothing to do with your host not appearing in the WebUI. In fact, it would be a little silly if a host is only shown if its reachable ;) First check that Nagios actually reads your config file (nagios.cfg: cfg_file/cfg_dir parameters). Be sure you have defined that host in your nagios config with at least one service (define host { .... }; define service { .... }). Also make sure your host/service definition has no "register 0" parameter and that your user is allowed to see the host (by a contact(group) or via "authorized_for_all_hosts" parameter in cgi.cfg).
