I don't know how you would do this on a win system but us nix users, we can use the native hostname with -f to get a reliable hostname.
<?php
$_SERVER["SERVER_NAME"] = exec('hostname -f');
?>

You can use php_uname("n") in Windows to return the host name. You may have worked this out already but it took my a blinkin age!
