As mentioned in the comment edit your question. With that information we are not able to help you.
From the fragment provided by now you should disable (comment out) a couple of lines from the httpd.conf file. The following directives should not appear there:
# directives until the closing bracket
You must enable the include of the
vhost.conf file after that, or check for it to be. This is most likely the reason you don't see anything but the default page. It is handled with something like the following:
Include path/to/vhost.conf (path and filename may vary).
Last not least check your hosts file and add
127.0.0.1 lc.intern for your browser to actually resolve your VH. Second reason it might not work.
Additionally your VH configuration is incomplete. It should look more like this
DirectoryIndex index.php index.html
Options -Indexes FollowSymLinks MultiViews
allow from all
CustomLog /path/to/tralala_access combined
(quick and dirty)
