SFC /scannow

IE6 and windows in general won?t let any access to the internet once it is connected. I tried to reinstall IE6 and it says there is a pending install of IE6 and you need to restart. Do that and the same message appear again? I tried to do a SFC /scannow and it asks for the CD which is SP1. I tried the original XP Home and it wanted SP1 so I put the CD in that SP1 was installed from and still it was the wrong CD. SO this type of scan cant be run. Is there a Registry hack to get rid of that pending install for starters?
