Scripting Limitations/unable to run certain commands in C:\WINDOWS\System32

I have the following script that I am deploying to a LogMeIn session with private session mode (using link to download LogMeIn agent and not calling card). The LogMeIn technician console and the agent are on the same machine. I am running both as the same AD user:

 

@echo off
C:\WINDOWS\System32\cmd.exe /c echo cmd test
C:\WINDOWS\System32\msg.exe "%username%" /time:0 Hello World

When I try deploying it via LogMeIn I will see the output of the 2nd line "cmd test" but for line 3 I get the following I get 'C:\WINDOWS\System32\msg.exe' is not recognized as an internal or external command, operable program or batch file.

 

 

Why am I able to run C:\WINDOWS\System32\cmd.exe but not C:\WINDOWS\System32\msg.exe?

  • I am able to run the 3rd line if I manually run it directly on command line outside of LogMeIn agent.
  • I still have this issue if I give UAC permission to the LogMeIn agent.
  • When I deploy a script that runs whoami I get the same output as running the command directly on cmd outside of LogMeIn.
  • If I deploy msg instead of the full path I get 'msg' is not recognized as an internal or external command,
    operable program or batch file. I don't get this when I run it directly on the command line outside of LogMeIn.

I'm stumped why this is happening and wonder if this means scripting is more limited than meets the eye.

    Hi 0000000000, welcome to the community.

     

    I have been informed that the best practice is to check if path C:\Windows\Sysnative\msg.exe exists and then refer msg.exe this way in the shell, otherwise you may call simply msg.exe. 

     

     

    It is recommended to use the following code in a CMD file:
    "
    if exist C:\Windows\Sysnative\msg.exe (
         C:\Windows\Sysnative\msg.exe blabla........
    ) else (
         msg.exe blabbla...
    )
    "

    I hope this helps.
