How to Create a Batch file for last logged on for a remote use

[Zealous637]

So I am looking to create some kind of batch file or script where I can click on it....it asks for the machine name, I enter it and then it displays the last logged on user. The following command
" wmic /NODE:"computername" computersystem get Username" gives me the desired results but I am trying to automate the process. I appreciate any help

Like this?

@ECHO OFF
SET MACHINENAME=%1
IF [%1]==[] GOTO SETNAME
GOTO END
:SETNAME
ECHO Type the machine name, press ENTER, Ctrl+Z, ENTER
FOR /F "tokens=*" %%A IN ('TYPE CON') DO SET INPUT=%%A
SET MACHINENAME=%INPUT%
:END
rem ECHO "%MACHINENAME%"
wmic /NODE:"%MACHINENAME%" computersystem get Username | find "\"
pause

Put that in a bat file and run it and it will ask for a machine name. The tricky thing is it needs a 3 step ENTER + Ctrl+Z + ENTER to exit the input mode. (that's the best I could do for a quick solution)

I made it so you can also call it with a parameter, then it won't ask for a machine name. Example:
C:\>GetLastUser.bat SERVER12
SERVER12\JOHN

You're welcome! It's always fun to write some code

Just curious.
Is this secure?
If anybody new the machines name they could work without a password off the previous users account. Or I'm I crazy.

you arent looking up the password. You are just looking up the username of a person who was last logged onto that machine. So yes its secure.

I think I understand now.
All you get is the last person logged in and no password.
Your also not able to use the computer under the last person log in without the password.
So after retrieving the last logged in person nothing can be done on this computer until someone logs in with a password.

My thought were if someone left the computer and forgot to log out once the bat file was run anybody could use the computer under the other person log in.

What makes me think of such things??

Paranoia?! The script only tells who logged in last. Nothing more nothing less. It's like going that machine and looking at the locked screen information, assuming the screen is locked. That will also tell you who is logged in. It's not much to abuse by that information.

Thanks for the information. I use paranoia as another layer of security protection.
