This error is related to the Network card change, probably by changing the server. "Network card not found (code: PE043)" This only applies to the Windows Network Card sensor. The WMI query for network traffic knows only one way to identify a network adapter: by its name. Unfortunately, this name is altered by Windows now and then. At the moment, the only thing you can do is to create a new sensor with the new name. You can try to create these sensors again now in the new server to see if the new sensors work better.
