I have a win server 2012 r2 server named ws7. from my other windows 2012 server that is currently our primary active directory server named ws4 I am trying to create a RODC for a remote office with limited bandwith
I am trying to "pre-create a read only domain account" and when I enter the name of the server it gives me the error"
The Specified computer name "ws7" already exists in the domain "mydomain.local"
The server ws7 is joined to the domain but i'm not sure what to do next
Precreating an account is used only when the object doesn't exist in Active Directory yet. From what you are describing ws7 is a member server of your domain already.
You'll just want to add the roles via the server manager on the new server 'ws7'.
