Neoware Stumped, computer account password not updating

[jpbeard]

This is an issue I've been having with the Neoware e100 & e140 thin
clients for the last few months. They keep dropping off the domain,
seemingly at random. We have determined that it may be after the 30 day
expiry date of the computer account password and for some reason the
thin client can't update it's password. In most of the related issues I
have researched on this group and on the web the cause is almost
invariably that the write filter is on. However, the write filter on
these thin clients is OFF. Neoware is at a loss to explain this and
it's getting very impractical to travel to two remote sites and rejoin
thin clients to our domain several times a month. We are currently
running the service pack 2 variant of their XPe image (their version
1.3) which also should have squashed any issues with the machine
password not being updated. I would really appreciate any help anyone
can give regarding this issue.

Also, I have found the following solution to disable the automatic
update of machine account passwords but I'd really like to see if there
is another solution.

I heard back from Neoware today, they think the issue lies in the write
cash. Most of our thin clients have the power cut to them at night,
then in the morning return to their last state. They think the new
machine account password might not be getting written to the flash
before the thin client looses power. They are currently working on a
solution involving either their proprietary ezRemote Manager or
possibly deploying a scheduled task on each TC to reboot each TC at the
end of the day before the power is cut. Hopefully this will remedy the
issue. Are there any thoughts on the best way to deploy a scheduled
task to a few hundred of these thin clients using a GPO or possibly the
AT command?
