Copied this from the ZCM 10 forum , but now ZCM 11.2 it seems I'm having the same issue. I've even rebooted the server and still do not see the inventory information for the Netware server. Notably, the log shows:

Unmanaged inventory servlet returned status: 200
and can't find what this is suppose to mean.

Unless I'm missing something (this is my first Inventory only device), I'm expecting to see the Netware server under Devices / Inventoried / Servers, correct?
