I found what i was doing wrong. When creating the wp-config.php I selected the wrong db-type. Now when using, pdo_sqlsrv, everything works properly.
Thanks for the fast reply, but i get this warning message on a fresh new installation i.e. i haven’t installed any plugin at all.
A question for you miguelgd. You say that you installed the latest version of wp (3.5.1) with the plugin for sqlsrv. Dont you get any error/warning messages when logged in at the dashboard. I have done as yuu but i get this warning messages = Warning: mysql_free_result(): supplied resource is not a valid MySQL result resource in.
