Usefull Windows Command-Line

I just came across this site for "Command-Line Kungfu". There are a lot of useful basic dos commands that can help every administrator (include hacker) to do anything with dos command line. Useful for anyone who doesn't has any vnc or rdp access to remote client pc (target pc) but has a dos access to destination pc.
We can combine with psexec command to do a remote command so we might be able to manage all clients pc with a single command without touching they box.
