All links in my site start with localhost?

This is my website http://173.214.165.83/. The home page shows, but all links start with localhost/wordpress, rather than the current address, which is 173.214.165.83.

The server is windows and runs IIS 7. WordPress is in C:\inetpub\wwwroot\wordpress. WordPress is installed by Web Platform Installer.

I’m new to IIS. How should I fix the link problem?

I hope I don’t have to reinstall wordpress.

You should be able to configure the URL that WP uses for the links in the backend, at Settings->General.
