Changing the BlackBerry Configuration Database
If you want a BlackBerry Enterprise Server to use a different BlackBerry Configuration Database, you must run the setup
application and specify the BlackBerry Configuration Database that you want the BlackBerry Enterprise Server to use.
When you change the BlackBerry Configuration Database, the BlackBerry Enterprise Server becomes unavailable and
users cannot send or receive messages on their BlackBerry devices. Organizer data synchronization occurs after you have
changed the BlackBerry Configuration Database.
Provisioning the BlackBerry Collaboration Service as a trusted application
If you install Microsoft Office Communications Server 2007 R2 or Microsoft Lync Server 2010 for instant messaging, you
must provision the BlackBerry Collaboration Service as a trusted application in Microsoft Active Directory.
If you add the Windows account that runs the BlackBerry Collaboration Service to the RTCUniversalServerAdmins group,
the BlackBerry Collaboration Service is automatically provisioned as a trusted application. The RTCUniversalServerAdmins
group is created when you install Microsoft Office Communications Server 2007 R2 or Microsoft Lync Server 2010.
If you do not add the Windows account that runs the BlackBerry Collaboration Service to the RTCUniversalServerAdmins
group, you must manually provision each BlackBerry Collaboration Service instance as a trusted application. If you change
the listening port number or if the FQDN of the instant-messaging pool changes, you need to repeat the manual
provisioning task. If you restart the BlackBerry Collaboration Service, you do not need to repeat the manual provisioning
task.
