Hi,

We recently installed a new Lync 2010 groupchat server.

In the Lync 2010 control panel topologies tab under the status, replication column shows a red cross mark.

Kindly help.

Thanks,

Amit.

Hi,

      I am still waiting for someone to answer.

Thanks,

Hi Amit,

Please try to use the command "Invoke-CsManagementStoreReplication" on the Lync server to force replication to start. And then use the command “Get-CsManagementStoreReplicationStatus” to verity the replication status. Hope that helps.

Hi,

      Kindly tell me on which server you want me to run this command. Front End or Group Chat.

Thanks,

Amit.

You should not be replicating to Group Chat, nor should you have a RtcReplicaRoot folder on group chat servers. Group is considered a trusted application and not part of the main Lync topology.  Only the Lync 2010 Core Components get installed on a Group Chat, and if you ran the deployment wizard on GC, you would see that nothing is deployed. Group will always show the red X and will always show false when you run “Get-CsManagementStoreReplicationStatus” .

Mike

Hi,

I just saw this question and you might have found a solution but here are my comments.

Lync 2010 Group chat does not have a local replication store installed, so replication will never some up.

can run the following script to disable replication for the group chat server in order to get a proper view from control panel.

1. Start lync powershell (as Administrator) on Lync Fe server.

2. Get the idendity of the application pool used by groupchat ( should be like this - TrustedApplicationPool<Server FQDN>) .... 
Get-CsTrustedApplicationPool
Identity             : TrustedApplicationPool:<ServerFQDN>
Registrar            : <Registrar:LyncPool FQDN>
..
RequiresReplication  : True
..
Applications         : {urn:application:microsoft.rtc.chat.channelserver}
..
PoolFqdn             : <Groupchat pool>
Version              : 5
Role                 : TrustedApplicationPool

3. Change replication to false by running:

PS C:\xxx> Set-CsTrustedApplicationPool -Identity TrustedApplicationPool:<ServerFQDN> -RequiresReplication $False

i hope it helps on yoyr problem.

Best regards
