Change password of domain computer account when UWF is enabled

Microsoft Windows-based computer that joined a domain uses the domain controller to periodically change the computer
account password for security purposes. If the thin client is a member of such a domain, password processing is applied
to the thin client as well. If UWF is enabled, the thin client will successfully change this password on the domain controller,
but since UWF is enabled, the new password will not be retained the next time the thin client is started. In this case, you
have the following options.

Set "1" to the DisablePasswordChange registry entry and disable machine account password change on the thin
client.

Refer to the Microsoft manual for each operating system to disable machine account password change on the
Windows based server. For example, to disable machine account password changes on Windows 2008 Server, set
RefusePasswordChange registry entry "1" on all domain controllers in the domain, not on each workstation. Even
after setting above, the thin client tries to change the password every 30 days, but it is rejected by the server.
