A system and method for communications between servers in a cluster. The system allows for point-to-point messaging to be used in a clustered environment to provide communication of services provided by each server or member of that cluster. Each server or member within the cluster advertises its services as before. If one of the receiving servers misses an advertisement, i.e. it becomes out-of-sync with the sending server, then the second (receiving) server makes a reliable point-to-point request to the first (sending) server asking for the missed services.
