I have heard rumors that data integrity is in jepordy when transfering 
files across routers using IPX.  I performed my own little test using a 
batch file to transfer a file to a remote 3.11 server, transfer it back , 
and check it's CRC, and do it again in a loop.  The server was thru 4 
cisco routers.  I got 5 instances over 5 hours of CRC's that didn't match. 
 The problem was first seen when our multiuser database files were getting 
corrupted by users across one router while in the presence of a noisy lan 
segment at that location.   I read that IPX does no error checking, but 
depends on the 802.3  CRC checking.  Should we expect errors with IPX when 
using routers or are we chasing a wild goose?
