TITLE   :XADM: Unable to Add a Directory Replication Connector to a Site
PRODUCT :Microsoft Exchange
PROD/VER::4.0,5.0,5.5
OPER/SYS:
KEYWORDS:exc4 exc5 exc55

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

 - Microsoft Exchange Server, versions 4.0, 5.0, 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

If you create an X.400 Connector or site connector for a new site and try to set
up a directory replication connector to the site, the setup does not work.

The site may not be displayed in the list of sites that are available for
directory replication under "Remote site name", or if you start the Exchange
Server Administrator program and, on the File menu, click New, click Other, and
then click "Directory Replication connector", the following error message may be
displayed:

   Mail connectivity must be configured to a new site before a new replication
   connector can be created.

CAUSE
=====

A directory replication route currently exists to the remote site. If you can
see the Site container for this remote site in the Exchange Server Administrator
program when you open it against a server in the local site, a directory
replication route exists through a directory replication connector to another
site.

RESOLUTION
==========

If you want to establish a directory replication connector directly to that
site, you must first remove the directory replication connector to the site that
currently updates your Exchange Server directory with the naming contexts and
objects from that destination site (the site that you want to establish a
directory replication connector to).

Exchange Server does not allow duplicate directory replication routes. Multiple
and duplicate messaging routes can be established for messaging redundancy, but
updates of the naming context of a site can only be received through one
directory replication connector.
