Abstract: Multiple remote computers, a PXE server, a DHCP server, and a deployment server are connected to a network. An administrator assigns certain remote computers to be employed, and these computers are rebooted in a network boot mode. Afterwards, a client program is downloaded to each of these remote computers from the PXE server with the help of the DHCP server. These client programs start to communicate with the deployment server for receiving a series of multicast deployment packets. These client programs use the contents in the deployment packets to build a system environment for these remote computers. Disk images, configurations of BIOS and CMOS of these remote computers are backed up in the deployment server in advance so that these remote computers can be employed efficiently when necessary.
