I restored my Dell Inspiron 600m (I know its an old model) by using the Operating System cd. Once i did that, the internet on the administrator account, that i use often, wasnt working. I have other profiles on that computer and the internet on those accounts work fine. Its just the administrator account that seems to be malfunctioning. Any clues on how to fix that problem? Any answers or suggestions would be great.

What version OS? XP/Vista/W7?
