A remote control system using in data sanitization field is introduced in this paper. The client downloads image files including starting configuration files and data sanitization files, then supports start-up operation of system and data sanitization. Data sanitization processes don't need the hard disk of client. The remote data sanitization system has network structure and processing flow. System performance including flexibility and efficiency is better than that of traditional system, and PXE protocol network structure means high speed and reliability. It is proved by practical application that the system is steady and reliable.
