Windows SAC (special administration console)

Installing Windows remotely I'll sometimes only be able to see the SAC> on the remote console output since I may not have a graphical viewer to do rdp or some other tricky way. Once SAC boots up I can access the command prompt by doing the following: cmd (It then gives you a name like cmd001) Switch to it: ch -sn cmd001 Now enter the user name, I usually don't enter any domain, and then enter the password.  Once done you can log in and run commands!!
