Can't see Security tab for a floder in XP

Can't see Security tab for a folder in XP?

If the security tab isn't visible on any of your folder properties in XP, you may have "Use Simple File Sharing" selected in your Folder Options.
Open Explorer and go to Tools>Folder Options.
Click the "View" tab and scroll to the bottom of the listbox with the heading "Advanced Settings".
Clear the "Use Simple File Sharing" checkbox.
