Windows 2000 MUI doesn't change logon screen language

Archived from groups: microsoft.public.win2000.setup_deployment (More info?)

>From past MUI deployments, I know that when I log on as a local admin
and want to change the MUI language, I am asked whether I want to set
this language as the system default. I click yes, and all user accounts
_and the logon screen_ change to that specified language.

Now when I do this on a fully patched Windows 2000 machine, it does
change all the users, but does not seem to change the value in
"HKEY_USERS\.DEFAULT", which is necessary for the logon screen to
appear in that language. When I manually change that value to the
desired language and reboot, everything works as expected. But the
control panel applet ("intl.cpl" ) doesn't change it.

Any information on this issue or possible explanations/workarounds?

Thanks, Claude
