Application server wont start

I am testing Lync 2010 Enterprise. We currently use OCS2007 R2.

I have all of the services starting just fine on the Pool servers except for "Lync Server Audio Test Service (RTCATS). I cant seem to figure out why.

I ran the following command:

Start-CsWindowsService -Report c:\servicestart.html

This is the output:

Start-CsWindowsService : Service "Lync Server Audio Test Service (RTCATS)" fail

ed to start within the expected timeframe: System error..

At line:1 char:23

+ Start-CsWindowsService <<<<  -Report c:\servicestart.html

    + CategoryInfo          : InvalidOperation: (:) [Start-CsWindowsService],

   DeploymentException

    + FullyQualifiedErrorId : Start failed.,Microsoft.Rtc.Management.Deploymen

   t.StartServicesCmdlet

Here is the output from C:\servicestart.html:

Error: Service "Lync Server Audio Test Service (RTCATS)" failed to start within the expected timeframe: System error..

I have 3 front-end servers, and all of them exhibit the same exact error. I have tried re-installing the OCSWMIBC.msi (WMI backwards compatibility - as suggested by another thread), but that doesn't seem to solve it.

Any help would be greatly appreciated!
