A computer system includes: a load information exchanging unit that exchanges load information on a regular basis to find a problem in a load distribution server on the other end of a link; a problem information communicating unit that transmits the information about the problem to a directory server (100); a problem information collecting unit (120) that receives the information and transfers the information to a problem information analyzing unit (130); and the problem information analyzing unit (130) of the directory server (100). As the problem information analyzing unit (130) determines that load accommodation links should be re-formed among load distribution servers, each load distribution server can secure two or more links. Accordingly, even when a problem is caused in a load distribution server, the connectivity among the load distribution servers is maintained, and there is no need to reconstruct the entire set of load distribution servers.
