This article provides brief information and steps to resolve the following error in BusinessLayerHost.log or in C:\ProgramData\Solarwinds\Logs\Orion:

 

SolarWinds.BusinessLayerHost.PluginInstanceAppDomain - Starting plugin: "Core Business Layer"
2016-04-11 10:32:15,818 [8] ERROR SolarWinds.BusinessLayerHost.PluginInstanceAppDomain - Plugin "Core Business Layer" failed to start.
System.IO.FileNotFoundException: Could not load file or assembly 'SolarWinds.JobEngine.Contract2, Version=2.8.0.52, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
File name: 'SolarWinds.JobEngine.Contract2, Version=2.8.0.52, Culture=neutral, PublicKeyToken=null'

 

Also check for this error (look for Attempt 1):


2016-04-07 08:52:03,094 [8] WARN  SolarWinds.Orion.Core.Common.ServiceHelper - Waiting for SWIS v2.0 start. Attempt 1, exception message: "Could not connect to net.tcp://stph-mgt-003:17777/SolarWinds/InformationService/Orion/certificate. The connection attempt lasted for a time span of 00:00:02.1528038. TCP error code 10061: No connection could be made because the target machine actively refused it 10.33.91.17:17777. "
