The Event Listener component is an event sink that is installed as a COM+
component to Exchange Server. You must perform the following
configuration tasks on the machine running Exchange Server:
- Create a user account for running event sinks and assign it the
appropriate permissions. See Setting up a user account and permissions for event sinks.
- Register the Event Listener executable (BIA_Exchange.dll) on the
Exchange Server machine. See Registering Event Listener.
- Create a COM+ application for Exchange Server and add the Event Listener
component to it. See Creating a COM+ application.
- Modify the Event Listener configuration file. See Modifying the configuration file.
- Enable the Windows Event Viewer to display Event Listener messages.
See Configuring the Windows Event Viewer for use with Event Listener.
An Exchange Server event sink requires authentication before it can
execute. Therefore, you must specify a Windows user account with
permissions to execute the event sink. This document refers to this
account by the general name Exchange_User.
Refer to the Microsoft Knowledge Base article 262054 (XADM: How
to Get Service Account Access to All Mailboxes in Exchange 2000) for
detailed information on creating the Windows user account.
The Event Listener component must be registered on the Exchange Server
machine with the Regsvr32 utility, as follows:
- Click Start --> Run. The Windows Run dialog box
is displayed.
- In the Open field, type the following:
regsvr32 installation_directory\BIA_Exchange.dll
where installation_directory specifies the location in which
you installed the BIA_Exchange.dll file (for example, C:\Program
Files\Exchsrvr\bin).
Windows displays a dialog box to confirm the successful registration of the
Event Listener file.
Perform the following steps to create a COM+ application on your Exchange
Server machine. This COM+ application is needed to run the Event
Listener event sink.
- Click Start --> Programs --> Administrative Tools
--> Component Services. The Component Services dialog box
is displayed.
- Expand the Component Services tree by clicking the plus sign (+) next to
it.
- Right-click the COM+ Applications folder under Component Services, and
then click New --> Application. The COM Application
Installation Wizard launches.
- Click Next on the Welcome dialog box. The Install or
Create a New Application dialog box is displayed.
- Click Create an empty application. The Create Empty
Application dialog box is displayed.
- Type BIA_Exchange in the Enter a name for the new
application field.
- In the Activation type box, click Server application, and then
click Next. The Set Application Identity dialog box is
displayed.
- In the Account box, click This user, and then click
Browse. The Select User or Group dialog box is
displayed.
- Select the name of the Exchange user you set up in Setting up a user account and permissions for event sinks, and then click OK. The user name is
inserted in the User field.
- In the Password field, type the password for the Exchange
user.
- Retype the password in the Confirm password field, and then
click Next.
- Click Finish to create the application and exit the
wizard. The COM+ Applications folder now contains a BIA_Exchange
application folder, with corresponding Components and Roles subdirectories
underneath.
After you have created the new COM+ application, you must add the Event
Listener component to it, as follows:
- Navigate to the BIA_Exchange application folder in the Component Services
dialog box.
- Right-click the Components folder, and then click New.
The COM Application Installation Wizard launches.
- Click Next on the Welcome dialog box. The Install or
Create a New Application dialog box is displayed.
- Click Install new component(s), and then click
Next. The Install new components dialog box opens.
- In the Files to install window, click Add.
- Browse for the BIA_Exchange.dll file you installed on the machine,
and then click OK. The wizard analyzes the file and lists
the Events component in the Components found window.
- Click Next, and then click Finish to exit the
wizard. The BIA_Exchange.Events.1 component is placed in
the BIA_Exchange application's Components folder.
The Event Listener requires a configuration file called
BIA_Exchange.ini. This file contains configuration properties
used by the Event Listener; Table 5 describes the properties you can need to edit or set.
Table 5. Event Listener configuration properties
Property
| Description
| Default value
|
CwEventID
| Identifies the last event ID used.
| zero (0)
|
CwEventUser
| Specifies the alias name of the Event Listener user. All events
are stored in this user's Inbox.
| CwEvent
|
CwAgentUsername
| Specifies the full name of the user account associated with the
connector. The Event Listener ignores events caused by this
user.
| CwAgent
|
CwAgentUserGUID
| Specifies the GUID of the user account associated with the connector (for
example, {31A42120 - 49B8 - 4B8F - A135 - 915C1AFF2BEC}).
The Event Listener ignores events caused by this user.
| N/A
|
CwEventUsername
| Specifies the full name of the Event Listener user. The Event
Listener ignores all events caused by this user.
| CwEvent
|
EventsTraceLevel
| Specifies the level of trace messages for the Event Listener.
| 0 (no tracing)
|
Make the following modifications to the file:
- Modify the CwEventUser entry to specify the name of the Exchange user
account you set up in Setting up a user account and permissions for event sinks. When the Event Listener receives notification of an
event, it sends an email message with event information to this user
account.
- Modify the CwEventUsername entry to specify the display name of the
Exchange user account.
- Modify the CwAgentUsername entry to specify the display name of the user
account associated with the connector's ProfileName configuration
property. This can be the same name used for CwEventUsername, or it can
be the name of a separate user account set up for the connector itself.
The Event Listener logs its error and trace messages to the Windows Event
Viewer. You must manually edit the Windows Registry to enable the
Windows Event Viewer to find and properly display Event Listener
messages.

---|
Incorrectly editing the Windows Registry can cause problems with your
machine. Use caution when editing the Registry. If you are
unfamiliar with the Registry, seek assistance from a Windows system
administrator. |
Perform the following steps to update the Windows Registry:
- If the Windows Event Viewer is open, close it now.
- Click Start --> Run, and type regedit in the
Run dialog box. The Windows Registry opens.
- Navigate to and highlight the key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\Eventlog\Application.
- Right-click to bring up the context menu, and then click New
--> Key. A new key is added to the Registry under the
Application key.
- Name the key BIA_Exchange.
- Right-click in the right pane of the Windows Registry to bring up the
context menu. Click New --> String Value. A
new entry is added.
- Name the new entry EventMessageFile.
- Double-click the EventMessageFile entry to open the Edit String dialog
box.
- In the Value data field, specify the full path name for the
BIA_Exchange.dll file (for example, ProductDir
\connectors\Exchange\dependencies\eventListener\BIA_Exchange.dll), and
then click OK.
- Right-click in the right pane of the Windows Registry to bring up the
context menu. Click New --> DWORD Value. A
new entry is added to the key.
- Name the new entry TypesSupported.
- Double-click the TypesSupported entry to open the Edit DWORD Value dialog
box.
- Type 7 in the Value data field, and leave the default base
(Hexadecimal) selected. Click OK.
