I cannot see Local Users & Group inside Computer Management. It is not visible and there is nothing listed. I am getting a error when I try to access it. The error is unable to access computer invalid syntax. I am a bit annoyed with the same and not able to locate solution for it. I need some help here through which I can restore the security settings. My OS is Windows XP Pro. It is a Media Center edition. There is a single user in the pc.
