[Samba] NT4 Terminal Server & samba-3.0.3-5 +

[John Schmerold]

After updating to samba-3.0.3-5,  I began seeing problems with our NT4 
Terminal Server. We are unable to copy or access large (200MB) files on 
the server. The file is an access file, but this doesn't seem to matter, 
I can't do a "copy bigfile.mdb \\cxhs\sys"
Small files don't seem to be a problem.

I've tried upgrading to samba-3.0.6rc2-2, no joy

We replaced nic, cable & hub, no joy

Any ideas?

My smb.conf is as follows:
[global]
force user = root
hosts allow = 192.168.10. 192.168.20.
hosts deny = all
interfaces = eth0 eth1

workgroup = workgroup

log level = 1
max log size = 1000

level2 oplocks = yes
remote announce = 192.168.10.255 192.168.20.255

strict locking = yes
oplocks = no

[sys]
         public=yes
         path = /home/sys
         read only = No

         path = /home/vol1
         read only = No
