XFOR: Exchange DSS Gets Event ID 133, 143, 168 Errors in Dirsync Cycle

The directory synchronization (dirsync) process fails when approximately 150 containers or more are set to be exported to more than one Microsoft Mail for PC Networks requestor. The process works for the first requestor, but fails with the second and subsequent requestors; they fail to get their updates. The following errors may be seen in the application event log when the logging level for the MSExchangeDX category is set to Maximum in the properties for the directory synchronization service:

This problem is due to a Jet page size limitation.

Jet limits page size to 4 KB. Jet tries to store all the information for a record in the page. If the combined data exceeds the page size, the data is stored elsewhere, and a 6-byte pointer is stored in the original page. After you add enough values/attributes, Jet can no longer add anything else, so it generates this error.

Microsoft recognizes the need for people to export large numbers of containers to more than one MS Mail (PC) requestor. We have modified the necessary Exchange Server components so that more containers can be exported.

This feature is available in the latest service pack for Exchange Server version 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base: The English version of this feature should have the following file attributes or later:

Components: Administrator Program and Directory Synchronization


NOTES:

• The updated Admin.exe, Dxa.exe and Dxamsg.dll files should be applied on the dirsync server experiencing this problem.
• The updated Admin.exe file should be applied on all Exchange Server computers, so that they are aware of the new schema.
• The updated Dxamsg.dll file should be applied on all servers that are used to check the event logs of the dirsync server that has this feature.

To apply this feature:

1. Stop all the Exchange Server services except the directory service.
2. On the dirsync server, type the following command at a command prompt, and then press ENTER:
   admin -i schema.csv -d servername -o schema.ini
3. Stop the directory service.
4. Copy the updated Admin.exe, Dxa.exe, and Dxamsg.dll files to the Exchsrvr\Bin folder.
5. Restart all the Exchange Server services.
6. Check the event log for successful data conversion or any errors. Note that the updated Administrator program will now be used for any changes to the Exchange Server services or when additional Recipients containers are added to the Export Container tab in the properties for the Remote DirSync Requestor object.
7. Copy the updated Admin.exe file to all Exchange Server computers.
8. Copy the updated Dxamsg.dll file to all servers that are used to check the event logs of the dirsync server that has this feature.

Reduce the number of containers exported to MS Mail (PC) requestors during dirsync to a number below 100.

This feature was first included in Exchange Server 5.5 Service Pack 3.
