Unlike Microsoft Windows XP Professional where the security tabs for the
folders and drives have been hidden and needs to be enable with certain tricks, Windows XP Home edition by default doesn’t have the security tabs
that allows users to configure and change the permissions and rights for Windows
folders and drives.
To unhide, view and display
the Security Tab in Windows XP Home edition operating system, Security
Configuration Manager Tool needs to be used. Security Configuration Manager Tool
is a tool set to configure security for a Windows NT-based or Windows 2000-based
computer. SCM has other features too such as perform periodic analysis of the
computer to ensure that the configuration remains intact or to make necessary
changes over time.
You can now see the security tab when you view the properties for the drive, file or folder. Warning though, misconfigured permissions will make your drives, files and folders inaccessible to everybody, including Administrator account will also be locked out from the resources. Beside, some advice on permissions setting is that Deny Permissions take precedence over Allow Permissions, regardless of your group membership, and Administrators are members of the User’s group, by default. So if you deny access to the User’s group, Administrators won’t be able to access too. So, try to Uncheck Allow, rather than using Deny.
