How to Check if you are running Lync Server Evaluation or Licensed Version

Posted by Ståle Hansen on 23/08/2011

At a customer site I was not sure if the PoC Lync environment was running Evaluation Version of the Lync Front End server or the Volume Licensed Version. They where looking to migrate from PoC to production so I had to make sure that the services didn’t stop in the middle of production.

Found a simple cmdlet to verify this: Get-CsServerVersion

  1. When run it will attempt to
  2. Read the registry value HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Real-Time Communications\{A593FD00-64F1-4288-A6F4-E699ED9DCA35}\Type
  3. Based on that registry value, the cmdlet will then report back the version number of the software and the Lync Server licensing information the local computer and report back one of the following:
    • That the Lync Server volume license key has been installed on the computer, meaning that no updating is necessary.
    • That the Lync Server evaluation license key has been installed, meaning that the computer must be updated.
    • That no volume license key is required on the computer. Updating from the evaluation version to the licensed version is only required on Front End Servers, Directors, and Edge Servers.

What if Evaluation Version is installed and you have to upgrade to Licensed Version?

  1. Log on to the computer as a local administrator
  2. Click Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Management Shell
  3. In the Lync Server Management Shell, type the following command and then press ENTER:
    • msiexec.exe /fvomus server.msi EVALTOFULL=1 /qb
    • Note that you might need to specify the full path to the file server.msi. This file can be found in the Setup folder of the Lync Server Volume media installation files.
  4. After Setup finishes running, type the following from the command prompt and then press ENTER:
    • Enable-CsComputer
    • Repeat this procedure on any other Front End Server, Director, or Edge Server running an evaluation copy of Lync Server
    • This procedure should also be performed on any Branch Office Servers that were deployed by using the Lync Server media installation files

Using Get-CsServerVersion will also show you

  1. What Version Number you are running
  2. What patches has been installed

    Hansen,

    Maybe I can pick your brain and experience on an issue we will face later coming from Livemeeting. Livemeeting has a built in feature to register attendee’s for a event published in Liveeting. We post this on a calender with a link to: https://www302.livemeeting.com/lrs/geoscape/Registration.aspx?pageName=12l8dz0fdg54092r . If you click on the link you see you can register yourself and then you will recieve a calender event to your email. I havent seen anything similar for LYNC2010? Do you how to go about on making this same feature for LYNC ?? It seems like a important feature? Dont know why is not built in?

    Thanks in advance for any help.
    Jerry

  3. [...] version of Lync Server to the real, live version of Lync Server need to run the cmdlet at the end of the upgrade process. Oh: and Enable-CsComputer can also be used to repair share permissions on your Lync [...]
