Question:
We attempted test and validation but it just seemed to spin and then timeout without any information
Answer:
Typically a timeout will indicate the remote IP is not IP reachable from the RN150 appliance subnet however, seeing 'Access Denied' in the assets section indicates the device was ICMP reachable. Access Denied means the remote server did receive the request however the device is stating that the credential did not have administrative rights.
You can also use wbemtest.exe (Windows utility included on all server/workstation versions of Windows) to test and validate WMI access.
