Symptoms

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.
