Hi,

I am trying to add third node to a Windows 2012 fail over cluster, but gets the following error.

The server 'DR.domain.com' could not be added to the cluster.
An error occurred while adding node 'DR.domain.com' to cluster 'domain-fc'.

Keyset does not exist

The User I am using to Add Node is Domain Admin, so it may not be a permission issue.

All nodes are Windows 2012 R2 VMs on

Hi Usman,

This error was created by azure or hyper-v cluster ?

Could you please try to find if there is  any related event log in cluster manager/windows event log  then post it here for us ?

Generally , when you add a server to a cluster, we strongly recommend that you start by connecting the server to the cluster networks and storage and then run the cluster validation wizard, specifying both the existing cluster nodes and the new node .

Best Regards,
