Problem with Domains

[lhnews]

I have a huge problem. I was trying to add one of my domeaines today after I freshly installed plesk on suse. But when I call the domain in the browser I get :
if you see this page hosting was not configured for this page...

But the DNS are set correctly and if I call the page from within Plesk I get the correct page displayed...

What is the best working OS for Plesk?
