When in or accessing MYOB Accountants Office Classic the following error "1104/Error reading file" or "1105/Error writing to file" may occur. 

These errors are generated by Microsoft Windows and can relate to network issues like a network connection failure which can occur in Remote Desktop applications.  Alternatively this error can also be related to files with a read-only attribute.

To reindex Accountants Office
  1. Restart the workstation as this may relate to a file sharing issue or error.

  2. Delete the 3 CADATA.* files and reindex all AO Classic modules. Refer to Re-indexing AO Classic

  3. Perform a reboot of the data server.

  4. If the issue keeps reoccurring after the workstations are left idling for more then 15 mins for example. It can be caused by Windows disconnecting the network drive to save resources.
