- 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.
