Note: Question was moved here from stack overflow after being closed as not being related to programming
I've searched through a number of similar questions on stack overflow but to my surprise I haven't been able to find an answer to this seemingly common/trivial question.
I've set up lots of websites in the past, but never on my own windows server. I have installed wordpress and I can access my website through my server's IP address over the internet.
I've typed in the rackspace name servers into godaddy last Saturday:

The name servers were obtained from the dns records on my rackspace for this domain.

Unfortunately I don't know how this all works behind the scenes so I may be configuring something wrong or missing something. I've configured the domain into my cloud server's domain management as seen here:

And I haven't done any other configuration (such as on my iis server). The problem is that I cannot visit my hosted site using the URL - only by the server IP.
