  1. Title:
  2. All domains should have at least two functioning domain controllers for redundancy

  11. Operation
  12.  
  13. Issue:
  14. The domain techlab.net has only one functioning domain controller.
  15.  
  16. Impact:
  17. In the event of a failure on the domain's only domain controller, users will not be able to log in to the domain or access domain resources.
  18.  
  19. Resolution:
  20. Add one or more additional domain controllers to the domain to handle authentication and authorization requests in case there is a failure on the domain's single available domain controller.

  40.  
  41. Impact:
  42. Restoring Active Directory Domain Services (AD DS) from infrequent backups can result in the loss of Active Directory data that was added, accidentally deleted, or modified since the last backup.
  43.  
  44. Resolution:
  45. To ensure that recent system state backups are available to recover Active Directory data that was recently added, deleted, or modified, perform daily backups of all directory partitions in your forest or keep the time between Active Directory backups to a maximum of 8 days.

  163. Issue:
  164. The primary domain controller (PDC) emulator operations master in this forest is not configured to correctly synchronize time from a valid time source.
  165.  
  166. Impact:
  167. If the PDC emulator master in this forest is not configured to correctly synchronize time from a valid time source, it might use its internal clock for time synchronization. If the PDC emulator master in this forest fails or otherwise becomes unavailable (and if you have not configured a reliable time server (GTIMESERV) in the forest root domain), other member computers and domain controllers in the forest will not be able to synchronize their time.
  168.  
  169. Resolution:
  170. Set the PDC emulator master in this forest to synchronize time with a reliable external time source. If you have not configured a reliable time server (GTIMESERV) in the forest root domain, set the PDC emulator master in this forest to synchronize time with a hardware clock that is installed on the network (the recommended approach). You can also set the PDC emulator master in this forest to synchronize time with an external time server by running the w32tm /config /computer:Oliver.techlab.net /manualpeerlist:time.windows.com /syncfromflags:manual /update command. If you have configured a reliable time server (GTIMESERV) in the forest root domain, set the PDC emulator master in this forest to synchronize time from the forest root domain hierarchy by running w32tm /config /computer:Oliver.techlab.net /syncfromflags:domhier /update.

  463. Issue:
  464. The "DsaCname" Domain Name System (DNS) alias (CNAME) resource record that ensures correct replication functionality is not registered on this domain controller. All writeable domain controllers must register this record.
  465.  
  466. Impact:
  467. Replication is not functioning correctly on this domain controller. If other domain controllers in the domain or forest are not able to resolve the CNAME record of this domain controller, the changes that are made on this domain controller will not be replicated to any other domain controllers in the domain or forest.
  468.  
  469. Resolution:
  470. Ensure that "DsaCname" is not configured in the "DnsAvoidRegisteredRecords" list, either through Group Policy or through the registry. Restart the Netlogon service. Verify that the DNS CNAME resource record "10f0d9db-d6e9-4516-84f0-52de9c55fe4c._msdcs.techlab.net", pointing to the local domain controller "Oliver.techlab.net", is registered in DNS.
