I did a windows repair (xp) and now I have a new problems. Isass.exe - system error - I looked up how to fix this, ran re-install disk again to go the repair mode, and now it is asking for administrator password, I never needed one before, how do I overwrite this and then take care of the isass prob.

Try this, hope it helps
