NSClient++ Help (#1) - Different results if command exectued in cmd.exe or through NSClient++.exe (#851) - Message List

Hello everyone,

I wrote a batch script that has to check whether a VirtualBox? VM is running or not. Here is the script:

@ECHO off
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" showvminfo "win732" --machinereadable > C:\Users\root\etat_machine.txt
FOR /F "tokens=* delims= " %%a in ('FINDSTR /I VMState= C:\Users\root\etat_machine.txt ^| FIND /C /I "running"') do ( set res=%%a )
IF %res% == 1 goto ok
IF %res% == 0 goto err
:err
ECHO WARNING: VM DOWN
EXIT /B 1
:ok
ECHO OK: VM UP
EXIT /B 0

I made some tests with a running VM. If I run this script directly in a CMD.exe window (check_vm.bat), I get VMState="running" so it's ok, my script returns OK: VM UP.

But if I launch it through the NSClient++ test mode (NSClient.exe /test injecting check_vm), I get VMState="poweroff" and therefore it returns WARNING: VM DOWN and my nagios thinks that the VM really is down...

Does anybody have a clue about solving this problem? Can it be a permission problem (NSClient not allowed to watch the VirtualBox? running VMs)?

I checked in services.msc, NSClient service is runned by Local System and therefore it should have access to all the compyuter... I don't understand what fails.

Can somebody help me? Thank you very much!
