PROBLEM:       While installing Windows 3.0 on the network, the user 
               receives an "Unknown copy failure" after unexpanding the 
               windows files with EXPALL.BAT and after running SETUP /N 
               (Network).  The users we have seen the problem with are 
               usually running Arcnet.
 
SOLUTION:      You can use the SETUP /I (ignore) /N (network) or you can 
               change the conflicting address/interrupt of the interface 
               card.

COMMENTS:      Windows evidently does some type of auto configuration to 
               see what IRQs and base I/O addresses are being used.  The 
               default base I/O address of Arcnet cards (2E0h) can conflict 
               with other addresses (in this case a video card) and cause 
               the windows auto configuration not to function properly; 
               thus, causing the error.  This is not just specific to 
               Arcnet; any type of interrupt, base I/O, or memory address 
               could also cause this to occur.
