A method and apparatus provides initializing a data processing system within a distributed data processing system. The data processing system receives data wherein the data is used to initialize the data processing system. The data processing system saves an image within the data processing system in a selected state after initialization of the data processing system, wherein the image is a saved image. The data processing system restores to the state using the saved image.

A method and apparatus for sending data from a first data processing system to a second data processing system in a distributed data processing system. A communications link is established between the first data processing system and the second data processing system, wherein the first data processing system receives identification information, such as caller identification information in the form of a telephone number and/or user name, as parts of the establishment of the communications link. D...
