  2. Backfill requests for some public folders are never completed on an Exchange Server 2003 computer

Backfill requests for some public folders are never completed on an Exchange Server 2003 computer

View products that this article applies to.

Symptoms

Backfill requests for some public folders are never completed on a Microsoft Exchange Server 2003 computer. Additionally, the Exchange 2003 computer continues to generate backfill requests. Eventually, the backfill requests may saturate the network.

Cause

This problem occurs if the local Exchange 2003 computer replica list for a public folder is out of sync with the information that is contained in the remote server rows in the replication state table.

In Exchange 2003, each public folder store maintains a replication state table to track the status of every replica in the store. The replication state table contains a list of replicating servers for each folder in the public folder store. Each row in the replication state table contains the GUID and the replication ID (ReplID) for the server. The local Exchange 2003 computer also maintains a replica list that includes the replicating servers that are known to the local Exchange 2003 computer for each public folder.

In either of the following scenarios, the local Exchange 2003 computer replica list becomes out of sync with the information that is contained in the remote server rows in the replication state table:
  • A non-existent remote server is referenced in the replica list.
  • An existing remote server is not represented in the replica list.
In either scenario, the local Exchange 2003 computer continues to generate backfill requests that are never completed.

More information

After you apply this hotfix, run the updated isinteg command. This command cleans up any replica lists that are out of sync and removes any unreferenced remote server rows from the replication state table. To run the updated isinteg command, follow these steps:
  1. Take the public folder store that is generating the backfill requests offline. To do this, follow these steps:
    1. Start Exchange System Manager. To do this, click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
    2. If the Display administrative groups option is turned on, expand Administrative Groups, and then expand your_administrative_group_name.
    3. Expand Servers, expand your_server_name, and then expand your_storage_group_name.

      Note The your_storage_group_name placeholder represents the storage group that contains the public folder store that you want to take offline.
    4. Right-click Public Folder Store, and then click Dismount Store.
    5. Click Yes when you are prompted to continue.
  2. Click Start, click Run, type cmd, and then click OK.
  3. At the command prompt, move to the following folder:
    Drive:\ProgramFiles\Exchsrvr\Bin
    Note The Drive placeholder represents the drive on which you installed the Exchange 2003 program files.
  4. Type the following command, and then press ENTER:
    isinteg -s server_name -test replstate
    Note The server_name placeholder represents the name of the Exchange 2003 computer.
  5. Type the number of the public folder store database that you took offline in step 1. Then, press ENTER.
  6. Type y to continue, and then press ENTER.
  7. In the Isinteg log file, verify that you receive one or more instances of the following error message:
    Replication state table has a row with no corresponding entry in the replica list.
    Note By default, the Isinteg log file for the public folder store is named Isinteg.pub. Isinteg.pub is located in the Mdbdata folder. You can view the file contents by using a program such as Notepad.
  8. Type the following command, and then press ENTER:
    isinteg -s server_name -test replstate -fix
  9. Type the number of the public folder store database that you took offline in step 1. Then, press ENTER.
  10. Type y to continue, and then press ENTER.
  11. In the Isinteg log file, verify that the number of errors that are reported equals the number of fixes that are reported.
