Example of a .cmd-script

SERVER\SHARE$ is where you keep the script, RoboCopy? and the NSClient++ files

@echo off
echo map drive
net use I: \\SERVER\SHARE$\NSClient++ /persistent:no
I:
echo.
echo Install NSClient++
if not exist "C:\Program Files\NSClient++\NSClient++.exe" goto skip01
echo removing old version
"C:\Program Files\NSClient++\NSClient++.exe" /stop
"C:\Program Files\NSClient++\NSClient++.exe" /uninstall
rmdir /s /q "C:\Program Files\NSClient++


:skip01
echo.
echo install latest version
mkdir "C:\Program Files\NSClient++
I:\robocopy /MIR I: "C:\Program Files\NSClient++"
"C:\Program Files\NSClient++\NSClient++.exe" /install
"C:\Program Files\NSClient++\NSClient++.exe" /start
c:
echo.
echo Unmap drive
net use I: /DELETE

Updating NSClient++

This set of script will allow you to sync your files from a centralize share to your NSClient++ install folder with logging info. After a successful copy, it will launch another batch script instance (reload.bat) to restart the NSClient++ service for the changes to take effect. You can then create a service command in Nagios to run the NRPE plugin script to have it automatically sync your NSClient++ folder. If it fails/pass, it'll even output the info along with what rev it was pulling.

Tested on Windows XP/2003/2008(32/64-bit) clients.

Place both of these scripts in the script folder and create an entry in your NSC.ini for them. Make sure you modify the source variable to reflect your central share.

Your central share should have a folder structure like this:
\           (Place your NSC.ini here)
\scripts\   (Place your scripts here)
