Hi Andrew You can create a new php file.
Let's call it customer.php and place it on the same level as index.php file af Magento. Put this code in the file.

error_reporting(E_ALL | E_STRICT);
$mageFilename = 'app/Mage.php';
if (!file_exists($mageFilename)) {
if (is_dir('downloader')) {
header("Location: downloader");
} else {
echo $mageFilename." was not found";
}
exit;
}
require_once $mageFilename;
Varien_Profiler::enable();
Mage::setIsDeveloperMode(true);
ini_set('display_errors', 1);
umask(0);
Mage::app('default');
$passwordLength = 10;
$customers = Mage::getModel('customer/customer')->getCollection();
foreach ($customers as $customer){
    //[Update 2012-04-19: thanks Michael]
    $customer->load($customer->getId());
    //[/Update 2012-04-19]
    $customer->setPassword($customer->generatePassword($passwordLength))->save();
    $customer->sendNewAccountEmail();
}
?>

then just call the page in your browser http://mydomain.com/customer.php After you finish delete the customer.php file from your server to avoid running it again.
