I have 2 servers and one is running as the primary domain controller, that has set up and been configured as a domain controller buttttt....
The second server wont join the domain as a domain controller, I run the active directory set-up and the error that i get while processing it at the very last step is :

Active Directory Installation Wizard
The operation failed because:
Active Directory could not create the NTDS Settings objects for this domain controller... Ensure the provided networks credentials have sufficient permissions.
"The RPC Server is unavailable"
Any help is much apreciated! thanks!
