A method and device provide for automatically reconfiguring a computer network in response to an operating system image migration from a first hardware platform to a second hardware platform. The method includes detecting a boot up command and in response, initializing a fix up utility, creating a new network configuration for the migrated operating system image and storing the new network configuration information; reading the new network configuration information and old network configuration information corresponding to the first hardware platform; determining if any of the new network configuration information corresponds to a new network interface controller and if any of the old network information corresponds to a non-assigned network interface controller; and if any of the old network configuration information corresponds to a non-assigned network interface controller, reassigning network interface controller identifiers from the old network configuration information to the new network interface controller.

A management sub-system is associated with a host computer system. The host system includes a network interface controller to facilitate transmissions between the host system and a distributed computer network. In addition, the management sub-system and host computer share an Ethernet network interface controller (NIC), which is assigned at least two different addresses. The management NIC includes decode logic that detects either of the addresses assigned to it, and routes the associated data packet to the management processor, or to the host processor. As a result, all management operations to either the management sub-system or the host system may be routed through the management NIC, while other standard operations may be routed through the host NIC. In addition, the management NIC may be used as a back-up or spare for the host NIC in the event it fails, or becomes overly busy.
