So i got a 2000 unattended build that works fine and I thought it might be possible to just substute the win2000 \i386 folder with the win2003 \i386 folder and everything might work fine for a win2003 unattended build. however that wasn't the case. when it goes to the 1st build screen for the initial file copy it complains about missing files, disk1, .dlls, etc..... I'm guessing its a little more complicated that that....
