A. If servers are booting from the network and are stuck at the DHCP stage, you need to first confirm (by checking the DHCP server) that they're receiving an IP address. You also need to ensure that the server is configured as a device in ADS, that it's captured for management by ADS (which is the state whereby ADS is allowed to send instructions to the device), and has a job applied to perform an action on the client (e.g., booting to the deployment agent or from its local hard disk). Otherwise, the server will simply appear to fail at the DHCP stage
