SYMPTOMS
========

When you attempt to upgrade a computer running Exchange Server version 5.5, the
following error message may appear:

   An unexpected error has occurred. ID no: c106fbf8

The Event viewer shows the following information:

   Event ID 50:
   MSExchangeIS [(147)] The database engine could not access the file
   called c:\exchsrvr\mdbdata\priv.edb

   Event ID 50:
   MSExchangeIS [(147)] The database engine could not access the file
   called c:\exchsrvr\mdbdata\pub.edb

   Event ID 11:
   MSExchangeIS [(147)] The database engine stopped.

   Event ID 10:
   MSExchangeIS [(147)] The database engine started.

   Event ID 2000:
   Verify that the Microsoft Exchange MTA has started.  Consecutive ma-open
   calls are failing with error 3051.

The above events may be repeated several times as the database attempts to stop
and restart. After you click OK to continue, the following error message
appears:

   Error: 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.
   Please contact Microsoft Product Support Services for more information.
   Microsoft Exchange Server Setup
   ID no: c1032c08

   Microsoft Exchange Server Setup was interrupted before your new software was
   fully installed. You can run Microsoft Exchange Server Setup in its entirety
   at a later time to complete the installation.

Click OK to quit Setup. If you attempt to restart Setup again, the following
error messages will appear:

   Microsoft Exchange Server Setup
   While attempting to stop the Microsoft Exchange System Attendant service, the
   following error was encountered:

   The service cannot accept control messages at this time.

   Microsoft Windows NT
   ID no 0xc0020425

Checking the Event viewer shows:

   Event ID 2000:
   Verify that the Microsoft Exchange MTA has started. Consecutive ma-open
   calls are failing with error 3051.

This event 2000 may be repeated several times in the event log. At this point,
the only choice is to click OK to quit Setup again.

CAUSE
=====

During the initial process when Setup is making sure the system is ready for
installation, Setup is trying to shut down the following services:

 - Message Transfer Agent (MTA)

 - Internet Mail Service

 - Event service

 - MDB

 - Directory service

 - System Attendant

Setup successfully shuts down the MTA and Internet Mail Service but fails to shut
down the Event service.

WORKAROUND
==========

To work around this problem:

1. Restart the server to stabilize the Exchange Server services.

2. Manually stop the event server service.

3. Restart Exchange Server 5.5 Setup.

MORE INFORMATION

Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 5.5.
