Problem conecting to MySQL

Hi. I trying to conect to MySQL with this line:

, <?php
//function Conec()
// {
if (!($link=mysql_connect("localhost","root","utopia")))
{
echo "Error conectando a la base de datos.";
exit();
}
if (!mysql_select_db("construccion",$link))
{
echo "Error seleccionando la base de datos.";
exit();
}
return $link;
// }
//$link=Conectarse();
//echo "Conexion con la base de datos conseguida.<br>";
//mysql_close($link); //cierra la conexion
?>

___________________________
and I get this response :
,
Warning: mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL client in D:\Inetpub\wwwroot\conexion.php on line 4
Error conectando a la base de datos.

I´m working with:
* Win XP
* IIS
* PHP 4.3
* AND MySQL Server 4.1

 

 $link=Conectarse();  

PHP:

You are calling a function thats non-existent!
try changing it to

 $link = Conec(); 

PHP:

 

Take a look at this.
