Computer will not even boot with the original Windows XP cd

Yesterday ran in to a problem on one of my computers in my network (only 3 in network). When the computer was turned off and then turned back on, Windows would not load because a file was missing or corrupted. At one point it even stated 2-Config files were missing (it was the Ntldr, and the ntldr.com). I attempted to reboot from the Windows CD after first changing the boot sequence to start with the CD ROM drive. It will not boot at all and I cannot figure out why. I cannot get into the recovery councel or anything due to the computer not booting with even the CD. Please help with any suggestions!
