On my home network I have 4 Windows boxes. 3 are downstairs and 1 is in my room. All of them are pretty lax on security since they have no internet connection. Anyway I can log into each one using null sessions (no user, no pass). So I'm pretty sure I can use shutdown's /m feature to remotely shut them down. Basically I need a batch file that will connect to each and shut them down. I was thinking it would go like this: step-BY-STEP 1.Get a list of computers (filter by //) and output (>) to file -net view > hosts 2.Establish NULL session with each computer -SET TARGET=blah (read from lines of file) -NET USE %TARGET%\IPC$ * /USER: (%TARGET% should be in \\HOSTNAME format) 3. If it succeeds, shutdown -IF ERRORLEVEL 1 GOTO :shutdown ERRORLEVEL 2 :skip, go back to step 2 But sadly, I suck with batch scripting so I really need your help. -Thanks in advance

If you only have 4 machines that need to be shutdown, why do you need the script to dynamically get a list of the computers or attemt a null session? Just create a batch script with 4 shutdown commands (1 for each computer). If a particular computer is on it will shut down. If its already off it won't matter. shutdown.exe -s -m \\computername1 -t -f shutdown.exe -s -m \\computername2 -t -f shutdown.exe -s -m \\computername3 -t -f shutdown.exe -s -m \\computername4 -t -f There are some other switches as well that you may want to investigate.
