Abstract: For computing nodes having a first programmable and comprising a first node and a second node, an update of the first node from the first programmable to a second programmable across an external network is initiated. In response to the update being interrupted, the first programmable is automatically reinstated on the first node by retrieving the first programmable from the second node across an internal network. The second node is automatically updated to the second programmable by retrieving the second programmable from the first node across the internal network in response to completion of the update of the first node to the second programmable.

Abstract: A method for performing remote diagnostics on a personal computer system in which the user calls a help desk representative who creates a computerized case file which includes modem telephone numbers, call and computer identification information. The representative also selects specific diagnostic tests, resident on the user's diagnostic disk, to be run on the user's computer. The representative creates a batch job which causes a computer to connect to the user's computer via modem and instructs the user's computer to perform the selected tests. The telephone connection is then broken. The user's computer reconnects with the help desk computer on completion of the tests and reports the result to the help desk representative. The representative then reviews the files and calls the user with recommendations. Certain necessary files can then be downloaded using a similar procedure.
