Hi,

I mount Windows Shared folder as (in my Debian Lenny):

mount -t cifs -o username=USER,passwd=PASSWORD,iocharset=utf8
//192.168.1.1/shared /mnt/shared

But sometimes, when I access some files, Windows 2003 server hangs with
a lot of errors log (in loop):

Is necessary restart server, because my laptop (only one with Linux in
network environment) do network very slowly with this loop erros.

I check my /var/log/syslog and see this:
