A networked computer device can be provisioned by customizing the computer device to contain a specification of a particular provisioning server. For example, a network interface device can be pre-configured and installed in the computer device. The pre-configuration of the network interface device may include embedding a provisioning service identification in the network interface device. The network interface device may be further configured to perform provisioning from a provisioning service indicated by the embedded provisioning service identification. In addition, or alternatively, the network interface device, or the computer within which it is installed, may be configured to authenticate with a provisioning server based on authentication information that has been embedded within firmware of the computer or network interface device.
