If so, how would I do this? I did restart the server, and continued with the tutorial, right up to: <A href="http://localhost/nagios/">http://localhost/nagios/</A> or <A href="http://203.59.254.217/nagios">http://203.59.254.217/nagios</A> However I get a 404 error page. Is this related to the error message above? Thanks for any help. Kind regards, Anthony 　 　</DIV></BODY></HTML>
