I have a single node Hyper-V cluster in which I am trying to add a second node. Both servers are identical hardware and are both installed with Windows Server 2012 R2 Datacenter.
When running the tests to validate the cluster configuration to add a new node, I receive the following errors preventing me from adding the new node. This error is received in the "Validate Cluster Network Configuration" section of the tests.
An error occurred while executing the test.
There was an error initializing
the network tests.
There was an error creating the server side agent
(CPrepSrv).
Unable to cast COM object of type 'System.__ComObject' to
interface type 'MS.Internal.ServerClusters.Validation.IClusterNetwork2'. This
operation failed because the QueryInterface call on the COM component for the
interface with IID '{2931C32C-F731-4C56-9FEB-3D5F1C5E72BF}' failed due to the
following error: No such interface supported (Exception from HRESULT: 0x80004002
(E_NOINTERFACE)).
Any advice on what to troubleshoot would be greatly appreciated.
