      Hi folks

      First of all apologies – I am 100% sure this is me being dumb however, I have spent the last few hours rtfm and still no joy and thought it would make sense to post here –

      Thank you in advance – cheers Nick

      ok, so I need to schedule service restart on 2k8r2 server using PoSH script.
      so – keep it simple and do something basic i.e. use spooler

      test.ps1
      start-transcript C:\Software_depot\Scripts\Logs\service.txt
      get-service spooler
      get-date
      stop-service spooler
      get-date
      start-service spooler
      get-date
      stop-transcript

      task is scheduled –

      run whether user is logged in or not and ‘run with highest priv’

      start program = C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
      arguments = -noprofile -noninteractive -nologo C:\Software_depot\Scripts\test.ps1

      domain account, with local admin rights and ‘Log on as batch’ set

      so that’s the setup
      test 1 – on execution of script manually with PoSH shell running as admin – all works services get, stop and start all work

      test 2 – run scheduled task
      get-service works
      start / stop service – fails

      here is the transcript

      ok. i now have it working.

      however, maybe someone could explain the logic.

      findings –

      Schedule created by Domain admin

      when scheduled task was created by a domain admin user account to run as a domain service account with local admin rights the resulting script failed to take actions such as start/stop service but could query service.

      Schedule created by the service account

      when scheduled task was created by the domain service account with local admin rights the resulting script executed correctly and services started/stopped as required.

       

      any light shed on this matter would really be appreciated.

      cheers

      Nick
