sorry not sure what you mean can you elaborate a bit please :)
configure.php files have this or similar at the top of the file
Yours are using an IP currently and you need to change them to the domain name
Code:
define('HTTP_SERVER', 'http://www.domain.com');
define('HTTPS_SERVER', 'https://www.domain.com');
define('HTTP_CATALOG_SERVER', 'http://www.domain.com');
define('HTTPS_CATALOG_SERVER', 'http://www.domain.com');
Your web server has to have the domain name entered for the account also
In linux, this is in the httpd file BUT most use a manager such as PLEX or cPanel to handle this
