If you re-provision a box post a hardware failure, then perform a system state restore, the server is NOT licensed (Even though the server is put back to it's original, licensed state as per a restore). This happens even if you do NOT select installing the agent as part of the provisioning process.
As far as I can tell, this means you would have to re-license the box. Is this a fault or is this by design ?
Please ignore. I found the information in the agent forum.
