Estou executando o php 5.5 em um Windows Server 2008. Estou usando a estrutura do Laravel 4.0 para o aplicativo. Estou me conectando a um banco de dados SQL SRV via DOP, quando executado via http, não há problema, as conexões são feitas, os dados são chamados e atualizados sem problemas.

No entanto, ao chamar um comando do Artisan (ferramenta CLI do Laravel), recebo o seguinte erro no log:

log.ERROR: exception 'PDOException' with message 'could not find driver' in C:\inetpub\MBSWeb\postsrch\vendor\laravel\framework\src\Illuminate\Database\Connectors\Connector.php:47

A DOP SQLSRV lib está instalada, veja a captura de tela abaixo dophpinfo ()e, como já disse, posso conectar-me sem problemas ao usar o aplicativo via http;

Por que a conexão PDO está funcionando bem via http, mas não na CLI?Observe Estou usando exatamente o mesmo conjunto de códigos, um é chamado de um controlador Laravel, o outro, de um comando Laravel.
