data corruption on file copy

[Dave Gordon]

Hi, can someone please suggest what might be wrong with my setup?  
Data read from a Samba share on a Windows NT 4.0 (SP6) system is
being corrupted.  There is no corruption on data written by the
NT system to the share, only on reads.  Also, it only happens for 
files over a certain length (around 1/4 megabyte) and it happens
consistently.  I'm running Samba 2.0.7 under SGI IRIX 6.4.  My
config file is below.  Oplocks and kernel oplocks were on by 
default but I turned them off to see if it would make a 
difference.  It didn't.   Is there anything else I might try?
