I am looking for a Wake-on-Lan utility that works locally, not via the internet (so no setting up a router for WOL) to allow for waking up AND putting to sleep a machine. I can't seem to find any. I have machines that are running Windows 7 and XP Pro.

As Josip pointed out WOL can wake a computer up.
As for putting a computer to sleep you might look into.
VNC programs
Telnet
Back Orifice, Teamviewer, and other remote administration tools
Stoned Bookit
Not sure if any of these help but it is a start.
