If you run winnt32.exe from the command line, to begin your installation, you can select the switch /makelocalsource. This will copy the i386 directory to the %systemdrive% and set the registry hooks for the i386 location to be there, instead of on the CD-ROM for future installs where the i386 directory is necessary. Is there a way to trip this switch in an unatended install, from the winnt.sif or otherwise? I have an existing autobuild CD, and this is a very desirable feature for my team, but I'm having no luck implementing it. Thanks.
