[Samba] help!!!

[David.Lee at bisus.com]

We are running RedHat Linux 7.3 with Kernel 2.5.8 (Upgraded from 2.4.18).
The Samba version is 2.2.5.
We still got the same problem as we used the kernel 2.4.18:
The command 'ls | wc -l' often returned incorrect numbers in a mounted
directory.
The following is the set up in /etc/fstab:

//usbbb01/Incoming /usr/local/customer/orders smbfs
username=mouse,password=.xxxyyyy
workgroup=usbdid01,uid=cignal,gid=users,port=445,debug=4,ttl=10000ms,rw 1 2

The 'usbbb01' is a Win2000 server.
The smbfs mount used to be OK when 'usbb01' was a NT server.

This issue really impacts our business!

Is any suggestion?

Thanks advanced!!!
