Need to shutdown client machine which are idel more than 1 hour.

Hi,

We are using windos 2003 server and xp3 for client macihnes.

We have more than 1000 machines avilabe which we use on daily basis. We have users who works in different- different shift.

When users logout from their shift, many of them forgot to shutdown their desktop which consume lots power and increase my compnay electricity bill.

Do we have any policy through whihc i can shutdown all the client machiens which are idle more than 1 hour.


Thx
