im trying to enable the "force shutdown from a remote system" option in secpol.msc
i want to be able to shut down my print server from upstairs. i added the account i want to the option, but when i click on ok it gives me the error thats shown in the pic.
how can i get around this in order to be able to sabe the change i made?

thx,
Apu

i used the administrator account to edit it and it still gave me the same message.
ive never imported a custom security template, how do u do it?
i tried gpedit.msc but i still got the same message.

thx,
Apu

EDIT: Id like to add that the pc i want to shutdown is WinXp Pro and the one that will be doing the shutting down is winxp home
