What is a "Host ID?"

A Host ID is an internal code that uniquely identifies a hardware device. FactoryTalk® Activation™ uses the Host ID to lock each software activation file to a specific hardware device.

To prevent activations from failing unexpectedly at runtime, do not lock activations to virtual network adapters, such as those used for virtual private networks (VPN) or virtual machines. Instead, lock activations to the Host IDs of fixed devices such as hardware network adapters or hard disk serial numbers. If you need help determining which network adapters are virtual adapters, contact your Information Technology department.
