SYMPTOMS
After you upgrade a computer running Microsoft Windows NT version 4.0 Service Pack 3 that was running the Microsoft Exchange Directory Synchronization Service (DXA) to Service Pack 4, the following errors appear in the Windows NT Application Event Log, and the DXA does not start:

Event ID: 249

Source: MSExchangeDX

Description: Error -1201 occurred while trying to create a new database.

- and -

Event ID: 172

Source: ese97

Description: MSExchangeDX ((276)) The database engine is initiating index cleanup of database 'd:\exchsrvr\DXADATA\XDIR.EDB' as a result of an NT version upgrade from 4.0.1381 SP3 to 4.0.1381 SP4.

- and -

Event ID: 177

Source: ese97

Description: MSExchangeDX ((276)) Database 'd:\exchsrvr\DXADATA\XDIR.EDB': The secondary index 'DisplayName_index' of table 'MapTable' is corrupt. Please defragment the database to rebuild the index.



CAUSE
After you apply Windows NT version 4.0 Service Pack 4, you need to rebuild the indexes of the DXA database to start the DXA, because the UNICODE sort order is changed in Windows NT version 4.0 Service Pack 4. After you upgrade the Windows NT version, the DXA doesn't rebuild the indexes of the DXA database automatically when you start the DXA.



RESOLUTION
If you defragment the DXA database, indexes are rebuilt, and the DXA starts successfully.
