Restart the web services:
# service httpd restart
# service httpd-e-smith restart
After you saved it don't forget to expand the template...
expand-template /etc/httpd/conf/httpd.conf
And restarting the services we don't actually use "service" anymore I would actually do...
/etc/rc7.d/S**httpd graceful
Where ** is a number, then do the same for the other
