Subnet Scans are not running and other polling appears to be broken as well. 


The IPAM.BusinessLayer.log has the error string below. 


**** 2016-02-09 09:55:41,750 [76] WARN  SolarWinds.IPAM.Jobs.JobScheduler (null) - ExecutionEngineExists: JobScheduler channel threw CommunicationException. Retries: 2

The JobEngine v.2 logs are missing or blank.


IPAM 4.3


The JobEnginev2 is corrupted/broken that causes jobs to not run properly. 


  1. Log in to your server as the Local Administrator.
  2. Turn off UAC (User Account Control) if it is turned on. This requires a reboot.
  3. Stop all services using the Orion Service Manager. (Start-> All Programs->SolarWinds Orion-> Advanced Features-> Database Manager)
  4. Click Control Panel > Programs and Features, and uninstall the following:
    • SolarWinds Job Engine v1
    • SolarWinds Job Engine v2
    • SolarWinds Collector
    • SolarWinds Information Service
  5. Navigate to C:\ProgramData\Solarwinds\Installers.
  6. Run the following msi files:
    • CollectorInstall.msi
    • JobEngine.msi
    • JobEngine.v2.msi
    • InformationService.msi
  7. Start all services using the Orion Service Manager. Give the site a few minutes to refresh and then wait for 2-3 polling cycles to check.
