We have some problems with MUI installad on XP Pro SP1.
Some users are logging in with a domain account on a client configured with the English language. The profile is stored on a network share.
When the same user will logon to another client configured with another language the profile is copied from the network share to the client. Now the language specific things are not translated. For example the Favorites in the startmenu are in Dutch Favorieten. The shortcuts on the desktop are in English Desktop but in Dutch Bureaublad. These names are not translated and therefore not available for the user on a client with different language configured with MUI.
