This topic explains how to install an update on an Enterprise Edition Back End Server or a Standard Edition server.

If a Back End Server is down for at least 30 minutes while you are upgrading it, users may then go into resiliency mode. When the upgrade is finished and the Back End Servers has again connected with the Front End Servers in the pool, users are returned to full functionality. If the upgrade takes less than 30 minutes, users will not be affected.

To update a back end server or Standard Edition server

  1. Log on to the server you are upgrading as a member of the CsAdministrator role.

  2. Download the update and extract it to the local hard disk.

  3. Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2013, and then click Lync Server Management Shell.

  4. Stop Lync Server services. At the command line, type:

  5. Stop the World Wide Web service. At the command line, type:

    net stop w3svc

  6. Close all Lync Server Management Shell windows.

  7. Install the update.

  8. Start the Lync Server Management Shell: Click Start, click All Programs, click Microsoft Lync Server 2013, and then click Lync Server Management Shell.

  9. Stop Lync Server services again to catch Global Assembly Cache (GAC) –d assemblies. At the command line, type:

  10. Restart the World Wide Web service. At the command line, type:

    net start w3svc

  11. Apply the changes made by LyncServerUpdateInstaller.exe to the SQL Server databases by doing one of the following:
