How Do I Get the Security tab in Folder Properties?
First, your hard drive must be formatted NTFS for this tab to show up.
Second, if you're running XP Pro, you must open Windows Explorer > go to Tools > Folder Options > View and uncheck Use Simple File Sharing. The steps are shown in the following screenshots.
Third, if you're running XP Home, Simple File Sharing is enforced by default and cannot be disabled. You must boot the computer into Safe Mode and log in with the Administrator account, in order to see the Security tab or go to: Windows XP Home, Simple File Sharing steps. Download the x86 (Intel) version of the Security Configuration Manager and save it to your hard disk. Double click the SCESP4I.EXE file you downloaded and extract the contents to a temporary location on your hard disk. Then open the folder you extracted the files to and locate the Setup.inf (Setup Information) file. Right click Setup.inf and select Install. After the installation is finished, reboot your computer. If the download link on the page, listed above, does not work, try this one: The Security Configuration Manager download.
WARNING: Adjusting the permissions on a drive, file or folder can lock even the Administrator account out of that drive/file/folder. Deny Permissions take precedence over Allow Permissions, regardless of your group membership. Administrators are members of the User's group, by default. Un-check Allow, rather than using Deny.
