I have abt 10 domains..
I have purchased a new dedicated Linux server..I have moved these domains on new server's IP address from the old server...
but now the problem is every site is opening the same page I dont understand why..
I have created the DNS through webmin and edited httpd.conf file as well but still single page is being opened on every site..

Can anybody help...

maybe this should be asking in technical and security questions?

Apparently you made wrong changes in httpd.conf and that's why. Remember that you need to create entries for domian with and without "www" prefix. I find myself ofted adding a domain"and forgetting about "www" entry, and of course in this case the latter will not work.

i think you need NameVirtualHost xxx.xxx.xxx.xxx:80 entry in your httpd.conf

just replace the x's with your server IP
