The machine is connected to the net with 802.11b wireless that connects to my router and DSL line. I have the original disks and keys for the install. After the 5th rebuild of the computer, the activation over the net stopped working. I had to call support and have them dictate a string to initiate the activation. Every crash/rebuild since that time has required the call to MS support. My office laptop and the other XP Home have never needed a rebuild, so it hasn't been an issue.
You have some serious issues, son, if you are reinstalling Windows five times on the same machine and are not a software developer.
I built a machine with a defective SATA cable and lost the installation several times. If you don't swap motherboards or hard drives, the activations can be done any number oof times.
