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


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.

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.
