PHP Noob Needs Help with SQL

[OctaneChicken]

Ok here's my problem "I CAN'T TO MY SQL DB". I'm using PHP 4.3.8, IIS 5.1, and MSDE 2000. I Get the following error

Warning: mysql_connect(): Can't connect to MySQL server on 'localhost' (10061) in c:\inetpub\wwwroot\index.php on line 6

Line 5 $link="localhost";
Line 6 mysql_connect($link);

Pls Help
