Abstract: A system is provided for the remote control of one computer from another in which selectable compression speeds are utilized to minimize overall screen refresh time. In one embodiment, an algorithm selection module at one computer chooses the highest compression available corresponding to a worst case scenario, followed by measurement of the compression time and the transmission time, with the ratio of compression time to transmission time being used to select a decreased compression, thereby to lower compression time and consequently lower the overall screen refresh time. By adjusting both the send time and the compression time on the transmit side, the above ratio can be made to equal one, which corresponds to the most efficient utilization of the available bandwidth and CPU power, which in turn translates into the quickest screen refresh time for the remote control operation.

Abstract: An automatic system is provided for dynamic diagnosis and repair of a user's computer through the utilization of a programmable interface to access and use relevant data in which a special script comprising a relatively small program first makes an inventory of hardware, software and configuration information relative to the user, his equipment and the network and stores this information in a single uniform object oriented database. A large number of system tools are also stored so that upon accessing the inventory and looking at any relevant data the script can call the available tools to automatically correct any user problem, whether it be compatibility of peripherals, software conflicts, providing missing software components, or correcting other problems, all on an automatic basis without user intervention or oftentimes without user knowledge.
