A method wherein a first user obtains an identifier for a desired destinatio n user, makes a request to a server for a data communication with that desired destination user, retrieves a computer network address from a directory entr y for that desired destination user, retrieves the source computer network address from the request packet from the first user, and sends requests to t he computers of both users for return of respective stored unique identifiers. When these respective unique identifiers are received at the server, a check is made to see that they correspond to only one respective entry in a database, and the server then sends a message to one of the computers to mak e a data call to the other computer. Users register initially and download a helper application which stores the user's respective unique identifier together with, in a preferred embodiment, a unique password, which is also stored in the respective entry in the database. The helper launches a NetMeeting application and passes its associated user's names. |
