Computer Account in AD

Hello,

I have a problem/situation with a Thin Client with Windows XP Embedded.

Background of the problem: the thin client has a flash memory, no hard
drive, and to save in that flash memory I have to do it manually (only
administrator can do it). When the regular user uses this thin client they
cannot save anything to it, so everytime they restart the thin client goes to
original point. So what i need is the user to log into that thin client with
an AD account. For this i logged in with administrator user and added that
computer to the AD domain and manually saved the changes in the flash memory.
Then users log into the domain with no problems.

Problem: after some days/weeks the user cannot authenticate in the domain
anymore on that thin client.

Solution I found: readd that thin client into the domain, then users can log
with no problems. Cannot solved it with netdom command to reset the channel
(it is already broken)

Cause that I think off: The computer account password is not being saved in
the thin client when it changes (during the regular 30 days) cause the user
has no automatic saving capabilities into the thin client. Because of the
domain controller having a different account password than the thin client
(the device has the original password each times it reboots) it cannot create
the secure channel with the DC. I get the error ID 5722 in the DC.

Please, Is there a way to solve this issue? Is there a way to set manually a
password for a computer account in AD or set it to never change?

Help will be really appreciate.

Thanks a lot
