Q174743: XADM: Cannot Install 4.0/5.0 KMS After Installing 5.5 Server

Article: Q174743
Product(s): Microsoft Exchange

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

If you run Setup to install a Key Management (KM) server version 4.0 or 5.0 in a
site that has a mix of version 4.0, 5.0, and 5.5 servers, Setup will fail with
the following error message:

  Unable to create Encryption-Cfg object in the site you are running
  Setup. Verify the Microsoft Exchange Directory is running then try
  again.

MORE INFORMATION
================

This is by design. This error occurs because Exchange Server version 5.5 Setup
creates the encryption-cfg object for the site, and earlier versions of the KM
server Setup program cannot utilize an existing version of this object.
