Active, couldn't classify: No WMI connection, now finished

[sukran]

We got an error for some windows devices as below in the WMIRunner / WML Classify

<result><error>Failure(s) with available Windows credentials from the instance.</error><error>The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)</error></result>

While did a test in ' test credentials and it has been successfully validated , how to figure out this

Check if Firewall is blocking WMI ports.  If not, try rebooting server.

Outside of checking firewalls I would confirm that your credential is mapped to the local admin group on the server. The test credential doesn't fully testing it end to end just that he credential in on there and a WMI connection can be done. Thanks.

Hi Robertgeen

How to do WMI connection test , can you please confirm that step by step

checking firewall means need to check Network security team ?

or windows firewall connection ?

Is there any other settings need to check for this?

Check the high ports - the Windows firewall might be blocking them. Discovery uses WMI which initiates on port 135 and the remaining communication occurs on high ports (49152 - 65535).
