We are trying to troubleshoot being unable to add a group of Nodes in one particular domain. Are there any logs in NPM that would give any information as to why they failed (i.e. timed out, bad credentials, etc)
All discovery logs stored here:
C:\Users\All Users\Application Data\SolarWinds\Discovery Engine\
If the problem visible on Add Node.ListResources this log can be helpful:
C:\Users\All Users\Application Data\SolarWinds\Logs\Orion\Core.BusinessLayer.log
If you're not making headway, our support team would be happy to help.
