To get the network boot process operational, you need the TFTP service that provides the basic file system at boot time. Get Tftpd from http://tftpd32.jounin.net/. You must download the latest version in zip format. Unzip it and store it in your favorite place. Then, you must setup the monster.
Run tftpd32.
