yup still reports Apache, I also see that you are trying to set up a forum software package.
Maybe the lightspeed was installed as a plugin and did not replace Apache.
just a thought...
this was a 404 page and can say anything you like in the reporting of the server software.
this information is in a file in the httpd-info.conf
in apache
#ExtendedStatus On
#
# Allow remote server configuration reports, with the URL of
#
http://servername/server-info (requires that mod_info.c be loaded).
# Change the ".localhost" to match your domain to enable.
#
<Location /server-info>
SetHandler server-info
Order deny,allow
Deny from all
Allow from .localhost
</Location>
so if you want it to say you are running lightspeed say soin the file.
