Abstract: An Integrity Server computer for economically providing a stand-in computer, replacing a failed server of a network. The invention provides methods for re-establishing connections between clients and servers, and communicating packets between network nodes, to allow the Integrity Server to stand-in for a failed server without requiring reconfiguration of the network clients when a server fails. In one method, the Integrity Server publishes the name of the failed server, in addition to its normal name, when the failed server becomes inaccessible. In a second method, a first channel accepts network packets addressed to the failed server, and forwards them to a second channel for service.
