Communications Server 2007 does not detect the changes when Unified Messaging dial plans or UM servers are added

This article has been archived. It is offered "as is" and will no longer be updated.
Symptoms
Microsoft Office Communications Server (OCS) 2007 does not detect the changes when Exchange Unified Messaging (UM) dial plans or UM servers are added. Microsoft Unified Communications (UC) enabled users who are assigned to this new dial plan do not have voice mail access. For example, they cannot leave voice mail or retrieve their voice mail. Additional functionalities, such as telephone number dialing, Subscriber Access (SA), and more, may not work correctly for UC-enabled users.
Cause
This issue occurs because invalid domain entries are present in the trusted domains list in Active Directory. OCS 2007 periodically updates the list of dial plans and UM servers. However, if any domain in the trusted domain list is unreachable, it assumes that this is a temporary network glitch and stops the update.
Workaround
To work around this problem, restart the rtcsrv process on all OCS 2007 front-end servers.
Resolution
To resolve this issue, apply the following update:
967831 Description of the update package for Communications Server 2007 R2: April 2009
This update fixes the update logic on the OCS 2007 front-end servers to be more resistant to invalid domain entries. It also enables OCS 2007 to detect the changes without requiring a restart.
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
