GPO - language settings problem

Hi there,

I have a 2008 server with XP SP3 workstations. Some users experienced that the default language ocassionally changes to English (from default Hungarian). Therefore I used a GPO script that I found on the net to set the keyboard layout:

CLASS USER

   CATEGORY "Keyboard Layout"

     POLICY "Keyboard Layout switching"

     KEYNAME "Software\Microsoft\Windows\CurrentVersion\Run"

       VALUENAME "internat.exe"

       VALUEON "internat.exe"

       VALUEOFF DELETE

       END POLICY

     POLICY "Keyboard layout"

     KEYNAME "Keyboard Layout\Preload"

         PART "Enable English" CHECKBOX

           DEFCHECKED

          VALUENAME "1"

           VALUEON "00000409"

           VALUEOFF DELETE

         END PART

         PART "Enable Hungarian" CHECKBOX

           DEFCHECKED

          VALUENAME "2"

           VALUEON "0000040e"

           VALUEOFF DELETE

         END PART

         END POLICY

END CATEGORY

I put the tick next to the Hungarian option. Now it works totally different: instead of forcing the Hungarian layout, now it's forcing English everywhere. I deleted the policy, but still the layout is changing to English every time someone log in. Every user has a Roaming profile. How can I change the default keyboard layout back to Hungarian?

I ran out of ideas.
