Lync Persistent Chat Error – User is not sip-enabled

Symptom: When you try to create a new chatroom from the Lync 2010/2013 client, you are redirected to a webpage that shows the following error:

User is not sip-enabled.

User is not sip-enabled

 

Solution: Turns out this is an issue with cross-compatibility between Single-sign on and 3rd party browsers.  Make sure you are using Internet Explorer and you should be able to login and manage your persistent chatroooms.

[Tutorial] Setting up and installing persistent chat for Lync Server 2013

Here is how to configure persistent chat for your Lync 2013 deployment.

  1. Login to your Lync Front End Server and start the Lync Server Topology Builder
  2. When the Topology Builder window opens, select Download Topology from existing deployment and select OK
    Download Topology from existing deployment

  6. On the Define the fully qualified domain name (FQDN) page, enter the FQDN your standard front end server and check Single computer pool.  If you want to deploy a highly available environment for persistent chat, you will need to deploy 2 new machines to put into a persistent chat pool and check Multiple computer pool.  It is not supported by Microsoft at this time to collocate the persistent chat service on the same machines in an enterprise front end pool.  Once done, click Next.

  17. At this point of the deployment, the infrastructure should be in place to actually push Persistent Chat out to your clients.  Next we will create a test group.
  18. Login to the Lync Admin Panel (Cscp)
  19. Select the Persistent Chat tab
    cscp - Persistent Chat

  23. Check Enable Persistent Chat and click Commit
    cscp - Persistent Chat - Edit Global Policy
  24. Next, we need to create the actual chatroom.  This step needs to be done via PowerShell, so open up the Lync Server Management Console.
    Lync Server Management Console
  25. Execute the following command
    New-CsPersistentChatRoom -Name “My test chatroom” -Category “Test Category
    Lync Server Management Console - New-CsPersistentChatRoom
  26. Next, we will assign a user to the chatroom, so execute the following command:
    Set-CsPersistentChatRoom -Identity “My test chatroom” -members @{Add=”sip:[email protected]“}
    Lync Server Management Console - Set-CsPersistentChatRoom
  27. Now, we are ready to join our test chatroom.  First, close your Lync client if it is already running.
    Lync 2013 Client - File - Exit
  28. Relaunch Lync, and you should see the persistent chatroom icon.
    Persistent Chat - Chatrooms
  29. Double click on the chatroom and try sending a message.
    Persistent Chat - Hello World
  30. Congrats!  If you have made it to this point, you should now be able to offer a new collaborative feature to your users at your organization! 🙂

Lync Server 2013 – All the channel servers are down

Symptom: After installing the Persistent Chat module for Lync Server 2013, you receive the following error when trying to manage Persistent Chat from the Lync Admin Web GUI (CSCP).

1 Warning(s) All the channel servers are down. All the channel servers are down.

Solution: Unfortunately, there are a few issues that could cause this.  Here are a few that I tried to get things working.

Solution #1: Ensure Cumulative Update 2 is installed.

  1. Download a copy of the Lync Update on the persistent chat server
    1. http://www.microsoft.com/en-us/download/details.aspx?id=36820
  2. Double click LyncServerUpdateInstaller.exe
  3. Click the Install Updates button
    Microsoft Lync Server 2013 Cumulative Update Installer for Persistent Chat
  4. Once all the updates have finished installing, click Close
    Microsoft Lync Server 2013 Cumulative Update Installer for Persistent Chat Updated

Solution #2: Add only 1 server to the pool, then add the rest

  1. Login to one of your front end servers and open up the Lync Server 2013 Topology Builder
  2. Delete the persistent chat pool you currently have deployed
    Delete Lync Persistent Chat Pool - Topology Builder
  3. Publish your topology
    Publish the Topology
  4. Recreate your persistent chat pool, but only add 1 server during the setup wizard.
    Create new persistent chat pool
  5. Once done running through the wizard, right click on your persistent chat pool and select New Server…
    New Server - Persistent Chat - Lync Topology Builder

    1. Repeat this until all the servers you wanted to deploy are part of the topology
  6. Publish the topology
    Publish the Topology

Notes: I couldn’t get event viewer to log anything referencing this error, which I thought was weird.   Additionally, I noticed that when originally deploying my topology, the topology wizard was complaining saying that “At least one machine must be active.” in order to successfully deploy the persistent chat pool.  I believe this is a bug in the topology builder and the only way I could get the topology builder to deploy properly, was by following Solution #2.  This ensured at least one server in the pool had a machine state marked as “Active”.

Here is a screenshot showing the persistent chat servers in an enterprise pool marked as inactive and topology builder complaining with the error “At least one machine must be active.”
