Zend Studio 6.1 et connexion réseau local MysQL

[JLC83]

Bonjour,
Sur notre réseau local (Server 192.168.1.4 windows 2003 - oui je sais - Poste de travail - unique pour cet aspect du projet 192.168.1.10 - sous 7Pro 64bits).
Zend Studio 6.1.
Sur le serveur : wampserver (dernière version) MySQL 5.5 php 5.3 Apache 2.2.8 phpMyAdmin 3.4.10
Dont un utilisateur 'jlc' dont client '192.168.1.4' Tous les droits (nous sommes en local ).
Propriété de la connexion sous Zend Studio :

• Driver : MySQL JDBC Driver 5.1 (pas de plus récent proposé par Zend Studio)
• URL : jdbc:mysql://192.168.1.4:3306/server
• User name : jlc
• Password : monMotDePasse

Au test de la connexion nous obtenons "Ping failed" suivi de l'incompréhensible message pour moi :

com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception:
