Odd Windows 2008 IIS 7 MySQL Problem

I have been following this post to install WordPress on Windows 2008 / IIS 7 / MySQL. Everything has gone well and the components have been installed. I have the default WordPress 2.7.1 theme enabled for testing.

However, here is my unusual problem. If I open up on the server IE and point it to http://localhost, the WordPress site comes up fine.

If I am at a different machine, and bring up the site in a web browser using http://servername, I can see the site but it lacks graphics or proper formatting, as if the CSS isn’t being applied properly. Also, when I highlight the main blog’s title, it actually links to http://localhost, even though I am at a remote machine. This is driving me nuts. Any help would be appreciated.
