Regional Options preference not applying

Hi,

I am attemtping to enforce UK region settings on some printer release workstations. I have set this using Regional Options GPP, RSOP reports that the setting has been applied successfully but alas when the account is logged in the keyboard settings are still set to US.

I have noticed that if I check the setting on the policy it says that the Standard language identifier isNot Specified could this be where the problem lies?

Any help with this is much appreciated.

Regards

Jimmy
