Firewalls off in both nodes SQL-1 & Sql-2
I created DNS Suffix in both servers as Testing.com
Remote registry and Remote administration is enabled in both nodes.
i enabled Failover clustering

In powershell command i tried this beow command

new-cluster -name sqlbag –Node SQL-1,SQL-2 -StaticAddress 1.2.3.4 -NoStorage –AdministrativeAccessPoint DNS

got below error:

New-Custer: There was an error adding node SQL-1 to the cluster
failed to access remote registry on sql-1.Testing.com .. Ensure that the remote registry service is running and have remote administration enabled.The network path was not found.

Note :Remote registry and Remote administration is enabled in both nodes.
