Hello

I would like to know what would be the best way to protect a
workbook(not the routine protect workbook), so that the workbook
becomes ineffective or uneditable if copied into any other
computer(even through LAN) or harddisk.

Only the author of the workbook should have the rights to copy the
workbook into another hardidsk or computer.

Can anyone suggest a way to do this?
Thanks
Rajesh
