Hi, I'm trying to add a node to an existing cluster but it fails the validation with the following:

An error occurred while executing the test.
There was an error validating that services required for failover clustering are running and configured properly.

An error occurred while validating local built-in users group.

I've checked the services and firewall but everything seems ok. Any ideas/suggestions?

The RPC server is unavailable

    Hello

    Thank you for your question and reaching out. I can understand you are having query\issues related to

    1. Please check if there a DNS entry for the cluster computer object ? and exist the object in the Active directory ? and make sure Admins have access to this object.
    2. Disable any Antivirus program or Windows firewall you may have for temporary purpose.
    3. Please check if your cluster a production cluster or just a test , If it is just a test , destroy your cluster and start over, It will save troubleshoot time and as now little hints are given.
    4. When you build the cluster did you run the cluster validation ? if so where there any errors in the log ? Navigate to C:\Windows\Cluster\Reports directory and open the Validation Report .MHT file look for warning / failed.
    5. Create a cluster.log file and post results using below command

    Get-ClusterLog –Node <CreateClusterNode>
