Hello all. I am trying to install a second domain controller to my network. When running Active Directory install, I choose “additional domain controller for existing domain.” I keep getting the following error when it attempts to create the ntdsa object on the existing domain controller.
The operation failed because:
The Directory Service failed to create the server object for CN=NTDS Settings,CN=XXXXXX,CN=Servers,CN=XXXXXX,CN=Sites,CN=Configuration,DC=XXXXXX,DC=com on server XXXX. Please ensure the network credentials provided have sufficient access to add a replica.
“A Service Principal Name (SPN) could not be constructed because the provided hostname is not in the necessary format. ”
Anyone come across this before? The user name I am using is a member of the Enterprise Admin group. Any help would be most appreciated.
Thanks very much.
