Host Name- PhpMyAdmin Problem

hello,

I am trying to fix a problem. Because of the host name of my dedicated server was set with the IP of the hosting company, I had headache. And after some research I changed /etc/hosts /etc/sysconf/network and /home/virtual/*/etc/hosts. Now the host name is as wished, sites can be viewed. But there must be some file I didn't modified, which causes that PhpMyAdmin is unreachable. By the way I should say, Ensim is installed on the box. Now I change the password for root, and restart the service. But when I click the link of MyAdmin I got Error Page. When I change the IP at the address line manually, I can view PhpMyAdmin, with my secondary DNS IP. And all the links at the PhpMyAdmin refers to the IP of the hosting company, so I can't do anything.
And I couldn't find the config.inc.php file from SSH, because I don't know where it should be.
Any help to fix the problem?

Thanks in advance,
