Wordpress Admin Link

Hello,

This is a wordpress question but I'm hoping all you wise people here can answer it for me. I setup my WP/ATA site using a server address prior to switching the DNS for the actual domain. The switch went fine, but I can access the wp-admin directory only if I still use the server address. Where do I go to change this? I can't seem to find it anywhere in the WP admin tool.

Thanks for the advice!
