NTA 4.2.2 is not compatible with NPM 12.2

Updated September 8, 2017


The production version of NTA 4.2.2 crashes with NPM 12.2 during startup of the NTA service. NTA 4.2.2 is therefore not compatible with the NPM 12.2.


  • NTA 4.2.2


The NTA log file NTA.BusinessLayer.log reports the following errors:

ERROR SolarWinds.Orion.NetFlow.Service.Program - NetFlowService will be abnormally terminated - Unhandled exception.

System.IO.FileNotFoundException: Could not load file or assembly 'SolarWinds.Orion.Configuration'


To solve this know issue, upgrade NTA from version 4.2.2 to version 4.2.3.

The workaround for NTA version 4.2.2 is to copy the file SolarWinds.Orion.Configuration.dll from the folder C:\Program Files (x86)\SolarWinds\Orion to the folder C:\Program Files (x86)\SolarWinds\Orion\NetFlowTrafficAnalysis.
