The Client Version Filter application is waiting for the Lync Server to start.

Cause: The Intelligent Instant Message Filter is not active until it is able to connect to the Lync Server.  You might not see this event immediately, depending on whether the Lync Server is slow to start.
Resolution:
None. If you see this event multiple times, you should examine the event logs to determine why the Lync Server has not started.
