If a link’s No Override option or Disabled option has been changed, Recovery Manager for Active Directory treats the link as having been deleted, and assumes that a new link was created with new options. This behavior is by design.
A primary restore is intended to recover the initial member of the SYSVOL replica set, only when the entire replica set has been lost. A primary restore should therefore not be used if there are two or more operational domain controllers in the domain. If there are other members in the replica set with which the restored SYSVOL can synchronize, a primary restore should not be performed, as it disrupts the replication of SYSVOL data.
For more information about primary restore, see the Microsoft article “Authoritative, Primary, and Normal Restores” at http://technet.microsoft.com.
Recovery Manager for Active Directory uses a TCP port to communicate with Backup Agent installed on the target domain controllers to be backed up. To change the Backup Agent port number, perform the following procedures.
On each target domain controller to be backed up, perform the following steps:
HKLM\SYSTEM\CurrentControlSet\Services\ErdAgent
%SystemRoot%\RecoveryManagerAD\ErdAgent.exe -I -P:3899
In this example, Backup Agent will use port 3899. When finished, click OK.
Start the Recovery Manager for Active Directory Console (snap-in), and then perform the following steps:

Important: If you are using a firewall, the specified TCP port must be opened. You must specify the same port number for all target domain controllers to be backed up. |
When recovering an Active Directory forest, Recovery Manager for Active Directory Disaster Recovery Edition automatically selects a DC in each domain to perform an authoritative (primary) restore of the SYSVOL folder. To select such a DC, Recovery Manager for Active Directory Disaster Recovery Edition uses a number of predefined criteria listed in this section. These criteria are listed in the order they are applied by Recovery Manager for Active Directory Disaster Recovery Edition. If no DC meets the first criteria in the list, Recovery Manager for Active Directory Disaster Recovery Edition tries to apply the next criteria. Recovery Manager for Active Directory Disaster Recovery Edition keeps going through the list of criteria, from top to bottom, until it finds a suitable DC.
Criteria used to determine if a DC is suitable for an authoritative (primary) restore of the SYSVOL (in the order of priority):
