The present invention describes a dynamic managing method, system and extended naming service framework for enabling service availability in a computer system comprising at least one or more client applications, one or more server applications for providing one or more services, and wherein the client applications use one or more services. The system further comprises one or more entities or pieces of physical equipment for providing one or more server applications and a management entity for supervising and recovering the entities or physical equipment. The framework provides a solution to the problem of locating and managing services within a system. The framework provides a centralised storage of information about all the services within a system, although it can also be a distributed solution as well. Source of information about the services are the service providers themselves or mapped information from HA notifications concerning physical equipment, e.g. a LAN port etc.
