I'm also having this issue.
Have recently migrated users from BES 5.0.3 to BES Express 5.0.3 and now suddenly the application event log is full of these;
Log Name: Application
Source: Blackberry Notification System
Date: 23/12/2011 13:46:32
Event ID: 373
Task Category: None
Level: Warning
Keywords: Classic
User: N/A
Computer: xxx
Description:
The description for Event ID 373 from source Blackberry Notification System cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
