After one week tried and error by IT manager (Teacher C. W. Su) in DEP, the original data in earlier old web server (WWW) has been recovered and the link in the domain name server (DNS) has been fixed! 

All colleagues or someone want to know about the old work in DAP, please refer to the following link:

If you have any question or further register the PC/domain in our DEP, please contact IT manager.
