I am deploying the Lync management pack in SCOM and trying to get healthy states for a Lync Distributed App.

I am getting the following error which I don't understand. Both Lync Front End's in the enterprise pool are on the same network, and I've never had any response group issues.

The passive Match Making Service cannot connect to the active Match Making Service. Access active Match Making Service: [front end 1] failed. Failure occurrences: 168997, since 18/12/2013 4:42:18 AM. Cause: There may not be an active instance at this moment or connectivity to that machine was lost. Resolution: Verify the Microsoft Lync Server 2010 certificate and Microsoft Lync Server 2010 installation and make sure that the active Match Making Service is reachable.

Any help would be much appreciated!
