I should have prefaced it by saying, if you have XP Pro there are other
ways. If you have XP Pro, you could use the Group Policy Editor to assign
other users to a specific group and specify what the group can and cannot
do. There is a learning curve with this. For information about the Group
Policy Editor please see the following Knowledge Base Article: http://support.microsoft.com/default.aspx?scid=kb;en-us;307882
If you have Home Edition, it's simpler to use third party software to define
what users can or cannot do.
