Hi,

I have a epson cx6500 scanner/printer which I have working with epkowa
drivers and sane-backends-1.0.12-2 on a RedHat 9 box. Saned is started
through xinetd and I have a Windows XP SP1 machine running SaneTwain
1.25 and scanning images with no problem.

Another Windows XP SP1 machine on the same local network refuses to
scan. Its running the same version of SaneTwain. When scanimage.exe is
started it tries to retrieve the scanners from the server and I see
the saned process started on the server (and a connection reported on
both windows and linux boxes using "netstat -na"). The scanimage
window is unusable (unclickable) for a while. After some time  the
window becomes usable and the devices dropdown is correctly populated
with the scanner's device.

Clicking "preview" or "scan", results in a pop-up which says: "Write
error 64, the specified network name is no longer available". When I
do a "netstat -na" on a windows box I can see that the tcp connection
is NOT there. The linux box (netstat -na) thinks the connection IS
there, the saned process is still running and is doing a read from the
socket which is (was) connected to the windows box.

Also, the "options" tab of the scanimage window is completely empty.
(On the working windows XP box it shows options).

Also, printing to the scanner/printer device from both windows boxes
causes no problems. The linux box also acts as the gateway to the
internet for both windows boxes. Surfing the web and downloading files
from both machines seems to have no problems.

I am attaching the log produced by running scanimage --debug on the
non-working windows box.

Is this a known windows problem? Has anyone seen anything like this before?

Any help is very much appreciated!

Thanks in advance,
Anton
