Hi Jeffery,
Thanks for your post. Based on my research, When you first create a cluster or add servers to it, you must sign in to the domain with an account with administrator rights and permissions for all servers in that cluster. The account you use doesn't need to be a Domain Admins account, but can be a Domain Users account that is in the Administrators group on each clustered server. If the account isn't a Domain Admins account, then you need to give the account or the group it's a member of the Create Computer Objects and Read All Properties permissions in the domain organizational unit (OU) that you plan to add it to.
Best Regards,
Ian Xue
