Great site for windows admins

Found this site while trying to figure out how to shutdown a remote computer with the shutdown command.
http://is-it-true.org/nt/atips/index.shtml
It looked pretty comprehensive. Hope this becomes a bookmark for all.
p.s. How do you remotely shutdown a comp with winXP pro using winXP pro?
I already tried shutdown -m computername -s

if you use psshutdown from systernals you can pass the admin user name and password to the remote computer so you dont get "access denied"

Thanks, I'll give it a try tomorrow.
