I put one over worked mostly with networks in a mixed Microsoft Windows NT andNovell Netw ar environment.

When this proc ess, a workstationis configured with general setting sufficient for most users. Specialsoftware is used to copy an image of that configuration. When a newworkstation or workstations is take to be configured the imaged isthen copied to the hard drive. For this procedure to work, theworkstation must have the same or very similar hardware as the headmaster workstation the image was copies from. Otherwise there willbe multiple errors and the administrator will spend time morecorrecting errors than he/she would have doing the configurationmanually.
