Click the Start menu, and then click the Control Panel option.
Double-click Administrative Tools-Local security policy.
Double-click Local Policy, the item that appears, and select User Rights Assignment.
Select and double-click to open the Force shutdown from remote system project.
Go to the Properties interface and click Add Users and groups in local security settings.
In the Select Users and Groups dialog box, click Advanced-Find Now, select Guest, and click OK.
You can see a "Guest" user added from the remote system Force shutdown property.
To turn off the computer remotely, use the "shutdown-s–m sunbird-t 30" command on the remote machine, and use the "Shutdown-r-T 0" command on the remote machine if you want to remotely reboot the computer.
The above is the open step for permission on the guest remote shutdown in the XP system. The guest's permission only has the administrator to have, therefore wants the remote shutdown, then must give the guest the corresponding operation authority to be able to do!
