On a Microsoft Exchange Server 2007 Service Pack 1 (SP1)-based server, you run the
following commands to perform a recovery operation in a cluster continuous replication
(CCR) and standby continuous replication (SCR) cluster environment:
- Restore-StorageGroupCopy -Identity <Failed Exchangeservername>\<StorageGroup> -StandbyMachine <StandByMachineName> -Force
- Disable-StorageGroupCopy -Identity <Failed Exchangeservername>\<StorageGroup> -StandbyMachine <StandByMachineName> -Confirm:$False
- Setup.com /RecoverCMS /CMSName:<Exchangeservername> /CMSIPAddress:<IPAddress>
However, the failover procedure does not finish successfully.
Additionally, you receive an event error 1002 that resembles the following
message.
Event Type: Error

This issue occurs when the following conditions are true:
- The CCR and SCR clusters belong to different Active Directory sites.
- SCR node is a cluster-based server.
- There is at least one domain controller that remains online at
the failed CCR site.
This issue may be caused by unfinished replication between the two Active Directory
sites for the
“msExchServerRedundantMachines” Active Directory attribute.
To resolve this issue, force domain controller replication
between the Active Directory sites, and then run the command again.
