Setting the Preferred Network Adapter

The "preferred network adapter" is the adapter used to communicate with Cryptographic Security Platform Vault. When encrypting the boot device, hcl checks to make sure that the preferred adapter is the adapter configured in the Bootloader. If not, the user is prompted to update the network configuration. This can be done either by using SetupHTBootloaderNetwork.ps1 or htblconf.exe. Both utilities clearly identify the preferred adapter when presenting options.

When using the GUI, it automatically opens htblconf.exe if the user agrees to updating the Bootloader network settings. This is meant to be a safety net that ensures that the Bootloader will be able to communicate with Cryptographic Security Platform Vault once the boot partition has been encrypted. However the user can choose to override this behavior.

When using the hcl command line, use the -N option on the hcl encrypt command to override the check for the preferred network adapter.
