I can browse http://localhost/ but not http://www. from web server?

Hi,

I’m having a bit of a problem. We have a website and we are currently running without any issues. When I open the browser, I can access the website on the server using http://localhost/ but when I browse to the actual website or the public IP I get a page cannot be displayed. Yet I can browse to any other website from that server, even another website that is being hosted in the same environment.

All our clients can access the website from the outside.

I have checked the windows firewall, the anti virus everything but still no luck.

Any Ideas?

Windows server 2003, IIS 6
