A mechanism is provided for configuring different computers of a network. Each computer plays a specific physic role (defined by an architecture of the network) and/or a specific logic role (defined by the applications running in the network). A reference model and a transition table are associated with each product to be installed in the network; the reference model specifies a target configuration for each role (defined by the components of the product to be installed), while the transition table specifies the actions required to reach each target configuration from each current configuration of the computers. A server identifies the role and the current configuration of each computer; the actions required to enforce the desired target configuration on the computer are then established and executed.
