Hi,
First:
you missed to tell us the version of samba you are using, and the
Software/OS of the client you are trying to copy your files from.
second:
I never had any problems moving large files around using w98/W2k/XP
boxes to and from the samba-servers i maintain (roundabout 12 machines),
except when bad/dying hardware/software was involved.
have you tried from another client?
have you updated ALL your clients drivers (not only the Nic's drivers)
to the latest versions?
have you checked if there are corrupted packets on your network
("ifconfig eth1" shows you statistics off packets on your server)
have you replaced any peace of hardware inbetween the server and the
client?
(if you don't have a spare-switch, connect client and server via an
crossover-cable...)
has your switch updateable firmware? if yes, have you updated it to the
latest version?
try to boot knoppix on the client and smbmount the shares then test if
then copying works.
Make shure your server is the masterbrowser at any time.
make shure ALL unused network connections in your clients are disabled.
(like ieee1394-network, or dvb-network, unused WLAN-Connetions and what
the hell modern windows versions think of devices being able to do
networking)

When i try to swap files between disks on my server using samba i get

Ive included a ethereal cap of the network during one of these
problems, and my samba config as attachments the errors are as follows:

Please Help im at a loss to what the problem is!

I have this problem all the time. Samba for me will cause the "The
specified network name no longer exists" (that's how it's worded for me,
not "available") and copy a zero-length file to the destination drive.
Reads from a Samba share are never any problem for me.
If you immediately retry the operation, and immediately say "Y" to
overwrite it, it will succeed.
If you do the above for the first in a series of files to be copied to a
Samba share, it will copy all the rest of them sucessfully.
The other thing that gives this error away is the "getpeername
failed... ...transport endpoint not connected. "
I thought I had this fixed, but after months, it has recurred. The fix I
tried was this (in smb.conf):
smb ports = 139
The explanation I got was that Windows try to connect to a server over
ports 443 and 139 nearly simultaneously, then use whichever one responds
first. Samba replies to both, and it might be that Windows has already
decided which it's going to use, and interprets the double reply as a
failure.
Use sendfile = no has also been suggested to me.
Frankly, this is embarrassing, and has kept me from pushing Samba
harder. When I ask about it, nobody seems to have a real answer.
