I have Lync Server 2010 and Active Directory installed on 2 different Windows Server 2008 R2 machines.

I have added a Windows 7 PC to AD. And I have added this computer to Trusted Application Servers Pool and published the topology.

I want to build an UCMA application to extend Lync Server functionality.

I have installed UCMA 3.0 SDK in the same computer where Lync Server is residing.

But, CMS Replication isn't happening and "Get-CsManagementStoreReplicationStatus" always gives Uptodate as "False" for my Windows 7 PC. I have even tried "Invoke-CSManagementStoreReplication" but nothing changed.

Also, this is the error message that I can see in the log file:
