What steps do I take to put a computer and its user back on a domain?

Server: Windows Server 2003 Standard

Workstation: Dell Optiplex 210

One of my workstations was sluggish, so I ran a software/hardware diagnostic. The hard drive failed the read and read verify test. I now have a newly purchased drive (Seagate-320gb). I don’t have any images, only XP SP3 OEM that came with the pc. I tried cloning the drive using Acronis with no success. Can someone help? Or Guide me to the right place?
