phpMyAdmin installation errors

Okay I'm having this problem with phpMyAdmin and installing it. I get this error every time I try to access it even though I KNOW the modules are installed right.
Code: 
cannot load mysql extension,
please check PHP Configuration
Documentation
Does anyone know if I have to change something?

I'm using PHP 5.0.3 with IIS 6 on Windows Small Business Server 2003.
