V-79-0-16072 "Final Error: 0x3ec8. Final error category: Other Errors" occurs when restoring a mailbox from an Exchange GRT (Granular Restore Technology) Backup Set.


Error



Final Error: 0x3ec8


Solution



This issue can occur in a Backup Exec Environment when the Media Server's Name has been changed or a new Media Server with a different name replaces the existing one, because the servers being backed up are still attempting to advertise to the original name of the media server. For example, when performing a direct or redirected mailbox restore from a GRT Backup, the remote Exchange Server will respond to all the media servers in the publishing list as soon as contact is initiated.  To see this information, first put the  Backup Exec Remote Agent Service in debug on the Exchange Server per the instructions in the following Technote:

How to enable or disable "debug logging" in Backup Exec for Windows Servers
http://www.symantec.com/docs/TECH23853


The debug log will be generated in the \Logs folder where Backup Exec is installed in \Program Files\Symantec\Backup Exec\Logs. Now, initiate a mailbox restore job.  When it completes, copy the debug log out of the logs folder and cycle the Backup Exec Remote Agent Service on the remote server to terminate debug mode.

Although the job may actually restore all the mail items successfully, this error will be logged at the completion of the job (In the debug log generated, look to the beginning of the restore job):

 

    [10192] 04/03/08 12:34:51 ConnectToServerEndPoint: dest=SERVER, service=6101
    [10192] 04/03/08 12:34:53 Could not create a BETCPConnection object from address: SERVER error=An error occurred during host address resolution: Error Code: 11001, System Error Message: No such host is known.
    [10192] 04/03/08 12:34:53 NrdsAdvertiserThread: connect to target=SERVER port=6101 failed


    And after this in the log:

      [10192] 04/03/08 12:35:53 ConnectToServerEndPoint: dest=SERVER, service=6101

      And then:

        [10192] 04/03/08 12:35:56 Could not create a BETCPConnection object from address: SERVER error=An error occurred during host address resolution: Error Code: 11001, System Error Message: No such host is known.
        [10192] 04/03/08 12:35:56 NrdsAdvertiserThread: connect to target=SERVER port=6101 failed
        [10192] 04/03/08 12:35:56 NrdsAdvertiserThread: Retrying in 60 seconds


      Throughout the restore, the remote server will continue to try to communicate with the original named media server, but that connection attempt will fail because media server name no longer exists.

      Resolution:

      1. On the server to which the restore is being directed, go to Start > All Programs > Symantec Backup Exec for Windows Servers > Backup Exec Remote Agent Utility.

      2. Select the Publishing Tab.  The name of the previous server may still be visible in the publishing list along with the current/correct server's name.  Remove the previous Media Server's Name and/or IP Address.  Add the new Media Server's Name and/or IP Address.

      3. Run the mailbox restore again to see if it completes successfully.  If it does not, proceed with the next step.

      4. Uninstall the Symantec Remote Agent through the Windows Add/Remove Programs Applet on the Exchange Server.  Reboot.

      Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.

      5. Open the registry (Start>Run>Regedit) on the Exchange Server.  Navigate to HKEY_Local_Machine\SOFTWARE\Symantec.  Delete the key Backup Exec for Windows if it still exists. Also, delete the \Backup Exec folder under C:\Program Files\Symantec if it is still present in Windows Explore

      6. From the Backup Exec Interface on the Media Server, open a new Selection List and look under User-defined Selections.  If there are any entries to the Media Server's previous name, remove those as well.

      7. Reinstall the Remote Agent on the Exchange Server and run another mailbox restore to confirm the issue has been resolved.
