Thread:Project:Support desk/help with making my domain visable when clicked/reply

If users from another PC should be able to see and use your wiki, you should not point to it with the domain name "localhost", but with the IP of the computer, on which MediaWiki is installed, or with a real domain name like "www.mediawiki.org".

You will also have to provide this domain name in one of the variables in LocalSettings.php; I think it was $wgServer.
