Hi Sam,
The local profile stuff should be in your C:\ drive in your %APPDATA% folder (you can just enter %APPDATA% in the path window to navigate to it).
This is generally disabled in organisations to stop this kind of meddling, but you may be lucky and it is just a hidden folder.
If it comes up with a permission issue, definitely raise it to your IT dept and ask them to go through the workflow or to grant your access (takes less than a minute if they were to reset normal.mxt for you).
