I am learning how to implement a failover cluster. I have 3VMs running Windows Server 2019 Standard Edition on all the VMs and it is not activated. I installed failover cluster feature on all the VMs. When I open the Failover Cluster Manager and start validating the configuration, I get an error that stats:
The server 'FQDN' does not have the Failover Clustering Feature installed. Use Server Manager to install the feature on this server.
This is weird because I did install it on all servers. Moreover, I can ping all the servers using their name's or IP Address.
