Backfill requests for some public folders are never completed on the Exchange 2000 Server or Exchange Server 2003 computer

Article ID: 892485

Article Last Modified on 10/26/2006

APPLIES TO

Microsoft Exchange 2000 Server Standard Edition
Microsoft Exchange 2000 Enterprise Server

SYMPTOMS

Backfill requests for some public folders are never completed on the Microsoft Exchange 2000 Server or Microsoft Exchange Server 2003 computer. The server continues to generate backfill requests. Eventually, the backfill requests may saturate the network.

CAUSE

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

In Exchange, 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 table contains the GUID and the replication ID (ReplID) for the server. The local Exchange computer also maintains a replica list that lists the replicating servers that are known to the local server for each public folder.

The replica list on the local server becomes out of sync with the remote server rows in the replication state table in either of the following scenarios:

A non-existent remote server is referenced in the replica list.
An existing remote server is not represented in the replica list.

In either of these scenarios, the server continues to generate backfill requests that will never be completed.

MORE INFORMATION

After you install this hotfix, you must run the updated isinteg command to clean up any replica lists that are out of sync and to remove any unreferenced remote server rows from the replication state table. To do this, follow these steps:

Take the public folder store that is generating the backfill requests offline:
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.
Click Start, click Run, type cmd, and then click OK.
At the command prompt, move to the following folder:

Drive:\Program Files\Exchsrvr\Bin

Note The Drive placeholder represents the drive on which you installed the Exchange 2000 program files.
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 2000 computer.
Type the number of the public folder store database that you took offline in step 1, and then press ENTER.
Type y to continue, and then press ENTER.
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.
Type the following command, and then press ENTER:

isinteg -s server_name -test replstate -fix
Type the number of the public folder store database that you took offline in step 1, and then press ENTER.
Type y to continue, and then press ENTER.
In the Isinteg log file, verify that the number of errors that are reported equals the number of fixes that are reported.
