This paper introduces strategies and techniques of using Ghost and applying DHCP-based network clone in computer laboratory management,which includes installation and configuration of DHCP server,production of startup disk of workstations,creation of mirror image files of hard disks and implementation of multicast clone.

This article introduced the installation and configuration of multicast clone software and how to clone the whole disc and other computers.

Through the Wake-on-LAN technique, the intelligent lab management system is to realize the remote administrators control the start of the computers in one or more rooms, and realize the Multicast clone of the WINDOWS 2000/XP which is booted based on the PXE, and finally to modify the information, net ID, IP and so on, of the computers .

This paper describes the method of only use flash disk to realize hard disk multicast cloning and the method of use hard disk protection software to protect system in the network environment,for it can make the maintenance of computer room highly effective.

5 enterprise version,the paper combined the DHCP service and TFTP document transmission with PXE network startup technique, achieve network multi-broadcast clone without the floppy driver and CD-ROM driver in the LAN.
