[Samba] XP clients disconnected during trasnfer of larger files tothe samba server

Any suggestions to look into, or more debug info required?

The box is running centos 4.3 final, up to date with the latest versions
of CentOS updates,, it's running something like 3.0.10 or .11 - can't
recall. 1:22 am. Off to bed... 

Thanks.

i'm having an issue when transferring large files to the samba servers
from an xp client - files about 1GB or larger. about 70% into the
transfer i get a network share no longer exists error and the transfer
fails. I can pull down from the server fine with no issues. The XP
machines are authenticating from a different Samba server though the
problem is with that machine as well. Error and config posted below:

Most of the non-default settings come from extended googling and come
back with possible suggestions to other issues I've seen, such as:

Ya we were. We were getting about 10-15 seconds of 'delay' when clicking
on a share, and this seem to fix it. Is this a smoking gun of some
problem? I had googled some errors in the logs we were seeing and this
was suggested to fix that problem and it did.

Again from trying to see what could help our problem

Hmm. OK. Well these machines have onboard nics (Tigon3
[partno(BCM95721)), and a quad port Intel nic, though they were not
detected on a duplicate machine by freebsd so we were using the onboard
nics, I'll get that switched to the quad intels, see if that helps.

Thanks Doug, much appreciated.
