I want to use sfc.exe for scanning for bad dll's and other files. sfc asked for a Professional CD not mentioning what service pack. I have XP Home SP3 installed and a XP Home SP2 CD.
Strange think is... i just solved it. When he asked for the Windows Professional CD I had to put in a Windows Home SP2 slipstream SP3 it worked. and after a few minutes he asked for a Windows Home CD so I put the original home SP2 CD in and it works.
