How to Resolve DNS Problems while Configuring a Web Site in Lion Server
If the dot next to the domain name is red while you’re still configuring your web site in Lion Server, the Server app can’t resolve the DNS name to your server’s IP address.
To fix it, try one of these options:
Change the domain name to something that will resolve. Check the spelling and form of the fully qualified domain name that you entered in the Server app and check your DNS server. You also can’t have two virtual hosts with the same domain name.
Assign another available IP address. You can assign another IP address if you’re using both of the Ethernet cards in a Mac Pro or add more. To do so, double-click the site in the websites list of the Server app and choose an IP address from the pop-up menu.
Check your port number to see if another service is using it.

If these solutions don’t work, something may be wrong with the DNS service. If DNS is running on the same server Mac, use Server Admin to adjust Lion Server’s DNS service.
