Given the weakness of Excel security I would say there is no way to ensure that
sort of protection can be found.

The best you can do to keep out unsophisticated users is to use a workbook_open
event to grab the computer name and close the workbook if not that specific
machine.

This would require enabling macros and having a contingency plan in the case
macros were not enabled.

See John Walkenbach's site for some tips.

1. Retrieving the machine name.

2. Using strongarm tactics to control Excel.

Hope someone can help.

Is there any way that a 'protection' can be put on an excel workbook,
that will allow that workbook to be run on a specific machine only?
