Hyper-V Cluster Shows Deprecated Server

I run a small 3 node, Windows Server 2012 R2, Hyper-V Cluster. When running the Validate Cluster utility I receive a warning under the "Validate Resource Status" heading that says:

"This resource is marked with a state of 'Offline'. The functionality that this resource provides is not available while it is in the offline state. The resource may be put in this state by an administrator or program. It may also be a newly created resource which has not been put in the online state or the resource may be dependent on a resource that is not online. Resources can be brought online by choosing the 'Bring this resource online' action in Failover Cluster Manager."

The server that is referenced used to exist but has since been decommissioned, the server has been shut down for several months and the Active Directory Computer account for it has been deleted. How do i fully remove this server form the cluster so that i don't see this warning anymore?

Does the now gone node show up in Failover Cluster Manager?

If yes, right click and EVICT.

It wasn't a cluster node, it was a guest VM.... Sorry for the confusion.

Open Hyper-V Manager and click on each node until the ghost is found. Delete it from the node.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

The Guest VM does not show in cluadmin.msc or the  virtmgmt.msc snap-ins on any of the cluster nodes.

On a node in an elevated PowerShell:

Get-ClusterGroup
Get-ClusterResource

Might be best to output to TXT and attach that to your response depending on the results.

Remove-ClusterResource "CVDC-RDS-1" -force

Or:

Remove-ClusterResource "Virtual Machine CVDC-RDS-1" -force

I suspect the second will do the job.

NapaValleyNetworksPresidentAuthor Commented:
the cmdlet "Remove-ClusterResource "Virtual Machine CVDC-RDS-1" -force" removed the reference to

Name         : Virtual Machine CVDC-RDS-1
State        : Online
OwnerGroup   : CVDC-FMAudit-1
ResourceType : Virtual Machine

but now, in the Failover Cluster Manager, the Information Column for the VM CVDC-FMAudit-1 says, "A virtual machine resource was not found in clustered virtual machine 'CVDC-FMAudit-1'." Clicking Information Details shows the attached.Information Details
I'm wondering if someone didn't repurpose the original CVDC-RDS-1 as CVDC-FMAudit-1.... the VM CVDC-FMAudit-1 is still up and reachable though.

the cmdlet

Add-ClusterVirtualMachineRole CVDC-FMAudit-1

Seems to have fixed it, thanks for your help!
