        RFCU-DC1 has a DHCP assigned address which is a problem for a domain controller so this needs to be addressed. Domain controllers must always be static assigned.  

        RFCU-DC2 has an unknown DNS address that should be removed. Domain controller should have own static ip address plus the loopback (127.0.0.1) listed for DNS and no others such as router or public DNS

         

        The system event logs may have some errors that will need to be dealt with. Generally, any found since last boot are still active and need to be addressed. Same for the DFS Replication event log.   

         

         

        If problems persist after fixes, then put up a new set of files to look at.
