Wrong port on redirection in WordPress

Hi

i am facing a problem. I recently moved an WordPress installation from one machine to another. On machine A it was running on port 88. Now on the new machine it should run on default(80?). My problem is every time i try to access http://localhost/wordpress/ it will redirect me to http://localhost:88/wordpress/. And that does not work.

I found a setting named siteurl in the options table and changed that but it did not do the trick.

Anyone now where i can change this setting?

Thanks
