TITLE   :XADM:Can't Log on to Exchange Information Store with GWClient
PRODUCT :Microsoft Exchange
PROD/VER::5.5
OPER/SYS:
KEYWORDS:exc55

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

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

SYMPTOMS
========

When you use the GWClient utility to open a mailbox, you may receive the
following error message:

   The attempt to log on to the Microsoft Exchange Server computer has failed.
   Component: Microsoft Exchange Server Information Store.

CAUSE
=====

This issue occurs because the private information store you are attempting to
connect to is configured to look at a different public folder server, and not
itself. This behavior can occur on Bridgehead servers that do not contain a
Pub.edb file.

RESOLUTION
==========

To resolve this issue, change the private information store to use itself as the
public folder server. To do this, follow these steps:

1. Open the Microsoft Exchange Server Administrator Program and connect to the
   server that the GWClient is connecting to.

2. Right-click the private information store on the server you are connected to,
   and click Properties.

3. Click the General tab, in the "Public folder server" box, enter the server
   you are working on, and then click OK.


You can now use the GWClient utility to open the mailbox.

NOTE: If the server does not have a pub.edb file, you must add one.
