We have a number of Dell OptiPlex 745's and 760's that have been rebuilt using the OEM media kits. The machines are reporting after different periods of time, that the machine has been tampered with and failed license activation. All are Vista.

First try removing the product activation and then using the Activation Backup and Recovery Program to restore the OEM SLP Product Activation.
See Windows Reinstallation Guide/A Clean install of Windows Vista:
Follow Step 2 (using the files I list opposed to your own as something is wrong with yours).
Then follow Step 11g and remove the product key and product activation. Restart your computer,
Once that's done follow Step 11b and restore the OEM product activation.
