CAU error when previewing updates

Question

_{Tuesday, July 18, 2017 8:12 AM}

Attempting to get CAU working for a 2 node HA cluster, both nodes running 2012R2. I get the following error when I "preview updates for this cluster" CAU:

The Microsoft.WindowsUpdatePlugin plug-in reported a failure while attempting to scan for applicable updates on node "<NETBIOS NAME>". Additional information reported by the plug-in: (ClusterUpdateException) There was a failure in a Common Information Model (CIM) operation, that is, an operation performed by software that Cluster-Aware Updating depends on. The computer was "<NETBIOS NAME>", and the operation was "ScanUpdates[Info,CauNodeWCD[<NETBIOS NAME>]]". The failure was: (CimException) Internal server error (500).  HRESULT 0x801901f4 ==> (CimException) Internal server error (500).  HRESULT 0x801901f4

The above error is repeated for both nodes (i.e. one <NETBIOS NAME> per node)

The "analyse cluster updating readiness" comes back all green (except yellow warning for machine proxy which wont apply to the node servers).  Windows updates run just fine (I can manually run updates just fine).

Any ideas?

Hi Anne,

I ran the above command for the same issue but it showed me 'Access is denied' after the first 4 lines of the 2nd command.
