Resolution

In order to resolve this issue, it is necessary to edit the cdrom drive class registrykey, using the registryeditor, as follows:

   * HKEY_LOCAL_MACHINE
         o SYSTEM
               + CurrentControlSet
                     # Control
                           * Class
                                 o {4D36E965-E325-11CE-BFC1-08002BE10318}

Remove any of the following registry entries against the cdrom drive class registrykey:

   * UpperFilters
   * LowerFilters
   * UpperFilters.bak
   * LowerFilters.bak

It is now neccessary to reboot the computer in order for the cdrom drives to be made visible.
