check_service_running.ps1

# Powershell script to check if a specific service is running
#
# Author: MrCrankHank
#
# The script uses the PsService.exe. You can download it from here:
# http://technet.microsoft.com/de-de/sysinternals/bb897542.aspx
#
# Place the PsService.exe in C:\Windows\System32 or somewhere else in your path var.
#
#
# Usage in PS
# .\check_service_running.ps1 -service <name>
#
# Usage via NSClient
# check_service_running=cmd /c echo scripts\check_service_running.ps1 -service $ARG1$ | PowerShell.exe -command -
#
# $service should contain the name of the service you want to check.
#
#
# Since this script uses arguments, you need to enable them in your nsclient.ini
# Something like this should do the job:
#
# [/settings/external scripts]
# allow arguments = 1
#
