baah..if u have to shutdown then why do u people use 3rd party tools??
just use ms task scheduler & shutdown..
call a batch file with a shutdown script..simple..
write that in a batch file & schedule that to exec at your time..
this will shutdown the computer..
& if yours connection is dialup type(bridged mode) then you will be disconnected from internet....if u are PPPoE connection..(always on) then the modem must be turned off manually..
