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

[Derrick MacPherson]

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.

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:
(FYI - transfering same files and such work fine via FTP) 
        
        My secondary server config:
         netbios name = 3Dsrv
         workgroup = VFX
         security = user
         server string = %h server (3D FileServer)

         username map = /etc/samba/smbusers

        smb log - i think this is relevant, though not sure:
