delete workbook if not authorized
 

Hi,

I want to delete or clear all contents of a workbook if it is opened on any
computer that does not belong to my company (not authorized). To determine if
it is an "authorized" computer can it could look at the domain ID or Windows
license owner (or whatever you suggest). If the computer is not authorized,
the flie is deleted or all contents deleted, etc.

I basically want to prevent this workbook from being used by unauthoized
people.

How can this be achieved?

Thank You!

It can't.

XL's protection methods aren't set up to provide security.

You can minimize the chances of unauthorized opening if you use
Office2003's DRM features. Note that that requires that authorized users
have access to an Windows Server 2003.

Otherwise, defeating XL's own protection methods are trivial.

Instead of using own DRM, why not use the free MS service?

Don't know. None of my clients who use DRM trust anything but their own
service.

OTOH, the vast majority of my clients don't use DRM.
