The two things I always screw up: permissions and DNS. If
your /etc/hosts isn't set up properly, and/or hosts.conf's URL entries
aren't correct, weird weird errors can happen. If something is set to
444 instead of 755 (as appropriate), other weirdnesses occur.

Are you using a www user? Make sure they're added as appropriate for the
file. 

I know *none* of this may be helpful, but I always check those and I've
usually screwed one up. Otherwise, is there anything
in /var/log/httpd-error?
