SYMPTOMS
When you attempt to upgrade to Microsoft Exchange Server 5.5, you may receive the following error message:

An unexpected error has occurred.

ID No. c106fdda

If you chose a fault-tolerant setup, you will receive an error message similar to the following:

Your upgrade did not complete successfully. Please restart your Microsoft Exchange services and your system will behave as it did before the upgrade was attempted.

If you did not choose a fault-tolerant setup, you must uninstall and reinstall Exchange Server 5.0 and then restore your databases from a backup copy.



CAUSE
This problem occurs when Setup is attempting to upgrade one of the databases that is inconsistent.



WORKAROUND
To work around this problem, quit the Setup program and restore the Priv.edb, Pub.edb, and Dir.edb databases if needed.

If a fault-tolerant upgrade was chosen originally, with the Directory and Information Store services stopped, run the following commands to verify the consistency of each database:









If a fault-tolerant upgrade was not chosen originally, with the Directory and Information Store services stopped, run the following commands to verify the consistency of each database:









For the database that is inconsistent, run the following command to attempt to force consistency:



If the directory, private, or public database does not become consistent, restore from a good backup, verify consistency, and rerun Setup.



MORE INFORMATION
The upgrade process to Exchange Server 5.5 upgrades all Exchange databases including the Priv.edb, Pub.edb, Dir.edb, and also the Xdir.edb in the DXADATA directory, which contains directory synchronization information if directory synchronization has been set up on this server.

If the upgrade process fails on the Xdir.edb, this database may be inconsistent because of an ungraceful shutdown. To verify the consistency of this database, run the following command from the Exchsrvr\Bin directory:

eseutil /mh \dxadata\xdir.edb |more

A portion of the screen output will show the state of the database to be either consistent or inconsistent.

Check for the Microsoft Exchange Server Directory Synchronization service. If the service is present and the database is inconsistent, you must attempt to make it consistent using the appropriate method:  Start the Directory Synchronization service, which attempts to perform a soft recovery and replay its log files. In Exchange Server 5.0, run the following command:

edbutil /d \dxadata\xdir.edb /r

 In Exchange Server 5.5, run the following command:

eseutil /p \dxadata\xdir.edb



If the Directory Synchronization service is not present, simply delete all the files from the \dxadata\.directory. NOTE: This database is not backed up with Online Backup utilities and can only be restored if there is an offline copy available.
