Here is a clip of the logs with many more items attempted but not shown. Can anyone direct to a source for the proper settings here? Should there be something here? I have seen other references to 1 in the help. There is blank section where the ProgID is in the KEPServerEX settings.

Does anyone know how to troubleshoot this? The items that are attempting to add have been verified as connected with Ethernet cables.
