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. Under normal circumstances, this will also create
the connector's user account.
- 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.
Exchange 2000 event sinks such as Event Listener run out-of-process and so
must have some form of authentication before they can execute.
Therefore you must create a user account
with permissions to execute the event sink. This document refers to
this account by the general name Exchange_User. In most
circumstances this account will also serve as the connector's user
account.
- Create a user account using Windows system administration tools. If
the user is going to be part of a domain (usually the case), the user account
must be added using Microsoft Active Directory. Otherwise, the user
account must be created using the computer's Local Users and Groups
program.
- Open the Exchange System Manager. You use this to set the new
accounts permissions.
- Navigate through the server tree until you reach your server. For
example, you might need to click through an administrative group and a server
group.
- Right click on your server. A pop-up menu appears.
- Click Properties
- Click the Security tab.
- In the Name dialog box, click Add and then select a
user from the list that appears.
- Select Full Control for the permission level.
- Click Okay.
Refer to the Microsoft Knowledge Base article 262054 (XADM: How
to Get Service Account Access to All Mailboxes in Exchange 2000) for
more information.
- Note:
- It may take a few hours for the change to take effect. If you wish the
change to take place immediately, you may reboot your Exchange Server.
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.
Event Listener requires a configuration file called
BIA_Exchange.ini. This file contains configuration properties
used by Event Listener; Table 6 describes the properties you need to edit or set.
Usernames are specified here so that Event Listener can filter out events
caused by itself, thereby avoiding the "ping-pong" effect.
Table 6. Event Listener configuration properties
Property
| Description
| Default value
|
CwEventID
| Identifies the last event ID used.
| zero (0)
|
CWEventUser
| Specifies the User logon name for the Exchange_User account. The
Event Listener sends its notifications to this account's mailbox.
| CwEvent
|
CwAgentUsername
| Specifies the full name of the connector's account. In most
cases this will be the same as Exchange_User, but it is possible to have two
separate accounts, as long as permissions on both accounts have been set to
have access to all mailboxes.
| CwAgent
|
CwAgentUserGUID
| Specifies the GUID of the connector's account. In most cases
this account will be the same as Exchange_User.
| N/A
|
CwEventUsername
| Specifies the full name of the Exchange_User account.
| 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 Event Listener receives notification of an
event, it sends an email message with event information to this user
account.
- Set the CwAgentUserGUID entry to specify the GUID of the user account
associated with the connector.
- Note:
- A convenient way of obtaining this value is to trigger the Event Listener and
then examine its event log entries. For example:
- Set the EventsTraceLevel to 5.
- Create an event registration in the Tasks folder (See"Registering for events". )
- Create a new task using Outlook. This will trigger the Event
Listener.
- Using the Event Viewer, examine the entry in the Application Log
corresponding to this trigger and locate the value of CwAgentUserGUID.
- If additional filtering
is desired, modify the CwEventUsername and CWAgentUserName entries to specify
the display name of the Exchange user accounts to be filtered out.
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.
