A rough guide to un-install and re-install Remote Access using the Mac Installers.
Insert Mac OS CD into machine.
Main directory of the CD will be displayed on screen, go to Installers.
Enter details, country, region...
If more than one OS is installed choose OS.
Add remove components.
Like Windows Add/Remove Programs but with tick boxes.
Put tick in Remote Access.
Drag box, Custom Un-install.
Click "Ok".
A window about close programs appears, click "Continue".
Special>> Restart.
Is the same as the above but instead putting a tick into Remote Access
Standard install
Click "Ok"
Special>> Restart.
