Mouse,
No need to get your knickers in a twist. You said "I copied the script and the .dll files to my local pc" but NT/2K/XP does NOT use and should not have the DLLs. Later in your script, you muck with Z: but Wintendos, which BTW are the only macines that need the DLLs, should not have their Z: drives messed with. You come on board here, demanding answers but you don't give us anything to go on, leaving us to stare at our crystal ball or pull the info through your nose.

You talk about the /F command but you say nothing about what version of KiX or OS you have. You could learn a thing or two about providing good info.
