XADM: 4.0 Server in 5.5 Site Does Not Function Properly

• Microsoft Exchange Server, versions 4.0, 5.5

SYMPTOMS

If you use the Setup.exe program in the Server\Support\Exch40\<platform> folder on the Microsoft Exchange Server 5.5 CD-ROM to install an Exchange Server 4.0 computer in an Exchange Server 5.5 site, and then apply Exchange Server 4.0 Service Pack 5 on the Exchange Server 4.0 computer, the server may no longer function properly. In particular, multiple errors related to the message transfer agent (MTA) or the directory may occur.

CAUSE

This problem occurs if the Exchange Server 4.0 database schema is not updated before you apply Exchange Server 4.0 Service Pack 5. The Exchange Server database schema is updated when you apply Exchange Server 4.0 Service Pack 2 or when you install Exchange Server 4.0a.

WORKAROUND

To work around this problem, use one of the following methods:

• Apply Exchange Server 4.0 Service Pack 2 before you apply Exchange Server Service Pack 5. For information about how to obtain Service Pack 2, please see the following article in the Microsoft Knowledge Base:

  Q152858 XGEN: How to Obtain Exchange Server 4.0 U.S. Service Pack 2




• Install Exchange Server 4.0 from a network share using the installation files from the Exchange Server 4.0a CD-ROM instead of the files from the Exchange Server 4.0 CD-ROM. Be sure to replace the 4.0a Setup.exe program on the network share with the Setup.exe program in the Server\Support\Exch40\<platform> folder on the Exchange Server 5.5 CD-ROM. After you install Exchange Server 4.0a, reapply Exchange Server 4.0 Service Pack 5.

MORE INFORMATION

Installing Exchange Server from an Exchange Server 4.0a CD-ROM is equivalent to applying Exchange Server 4.0 Service Pack 2 on an existing Exchange Server 4.0 computer.
