I can't change anything in the control panel. My computer says I may have not sufficient permissions to access the item.

We have tried everything we can think of changing the time in our computer.  Whenever we click on the small box in the lower right corner, he says - "Windows cannot access the specified device, path or file.  May not permissions to access you the item.  In addition, we are unable to add or remove programs or making changes through the control panel.  Help

All the problems you describe are problems that could occur if the user that you are connected without administrator privileges.  The quick check of administrator privileges must right click on the button 'start '.  If "Open All Users" is one of the choices that appear, then you have administrator privilege.  Otherwise, you must connect to your machine like the built-in 'administrator' or a user in the group "Administrators".

Assuming that you have administrator privileges, things get more complicated.  User rights can be granted or denied to any user - even administrators - by group policy.  If you are an administrator and you have XP Pro, then you might be able to check or change the user rights by using the Group Policy Editor (from-> Run-> "gpedit.msc").  Search in the:

Computer configuration-> Windows settings-> security settings-> local policies-> user rights

path.  One of these user rights is "Change the System Time".  If your XP Pro machine was never part of a domain, I would consider also running a program anti-malware on your system.

If you have XP Home Edition, you don't have the Group Policy Editor.  You will need to check / adjust / modify your user rights by using the command line program "NTRights" provided with the Resource Kit.  Problems like that with XP Home would raise my suspicions that you have a malware infestation.
