yeah, fair enough. although when i did it to change a keyboard layout from us to uk across a network i did it from the users logon script calling a reg file that made the change silently and the users never even noticed, nor did it have any adverse effect on logon performance, even though the change is getting applied each time anyone logs on.
so, will you have your own copy of the profile thats been made in the US on your local server or something?
