Abstract
When a computer as a logical connection destination which detected a search objective user issues a search request to first one of computers which established logical connections associated with the search objective user, the first computer selects users who used a searched computer in a use time of the search objective user, and executes the search request over the computers which established the logical connections associated with the selected users. The same search request is sequentially carried out over m candidates of the logical connection originator computer of the searched computer down to an m-th computer. Search results (a computer identifier of the searched computer and user identifiers of the selected users) obtained by the m computers are collected in the respective computers and returned to the logical connection destination computer in an order opposite to the search request order. With use of information widely obtained in a conventional manner, a connecting path from the logical connection originator computer to the logical connection destination computer can be searched.
