1. A network map diagnostic tool operated by a user of a computer coupled to a computer network interface server, wherein said computer network interface server is coupled to a plurality of computer network entities on a computer network, said diagnostic tool comprising: a configuration file generated at said computer network interface server, said configuration file comprising a network address for each of said computer network entities and graphical data for depicting and positioning said computer network entities and said computer on a display; means for retrieving said configuration file from said computer network interface server; a graphical interface which graphically displays the computer coupled to said plurality of computer network entities on the computer network from a perspective of said computer, wherein said graphical interface is generated at said computer based on said configuration file and includes a first graphical coupling that couples the computer directly to a first network entity and a second graphical coupling that couples the first network entity directly to a second network entity; means for allowing the user to select said second network entity; means for testing the connectivity from the computer to said second network entity; and means for graphically displaying a status of said connectivity using the first graphical coupling to display the status of the connection between the computer and the first network entity and using the second graphical coupling to display the status of the connection between the first network entity and the second network entity, wherein the information in said configuration file is limited to maintain network security.
