    Hi
    I was trying to run wordpress on IIS 8 PHP 5.4.X mySQL 5.2.x

    Warning: mysql_connect(): php_network_getaddresses: getaddrinfo failed: No such host is known. in ...\wwwroot\wordpress\wp-includes\wp-db.php on line 1038

    The only things I found about this error seem to hint at DNS Resolution Errors or generell Access Problem to the database.

    I've wrote a Little php scryipt manually that Access the DB and get's some data out of a table I created manually and put some data in there to test the Connection. The PHP file showed me the table data without a Problem using the same DB and user from the same Server, even put it in the same Directory where the wordpress files are.

    Doesn't make a diffeerence if I put an IP or the host Name into the Connection configuration file.

    I assume it's somehow a Problem with IIS8 or the PHP Installation Since ist also Happening with other applications I tried out.
    Any Ideas where / what to look for?
    The Webserver has 2 NICs, one for public Access and one for the internal Network that connects to the Database.

    I've made a few checks.
    $_Server["SERVER_ADDR"] = Doesnt work on Windows / IIS
    $_Server["LOCAL_ADDR"] = is the same as $_Server["SERVER_ADDR"] on unix, does give the external IP
    $_SERVER["REMOTE_ADDR"] = Returns external IP
    gethostbyname($_SERVER["SERVER_NAME"]) = Returns external IP

    I geuss that's the Problem. Trying to search the MySQL Server on the external Network doesn't work. It is not accesssable from the outside.

    So how do I Change this so that the internal IP get's used?
