Installing Lync 2013 CU1

Applying Lync server update 2013 CU1 can be a challenge. There is generally documentation on the process but it is easy to miss steps and it’s always nice to be assured that someone else has successfully applied the updates. In my case I bricked both my Edge and the FE server. I didn’t follow instructions. so without further delay. This is the rough and tough steps to apply CU1 for Lync 2013. Which by the way rocks for mobility. It is nice to have sip calls that actually work! and Video Calls!


Here is the Lync 2013 CU1 Update

  1. Download the Lync Updated Installer




Then run the installer and determine what updates need to be applied



Apply the updates and get green check mark and a required reboot here:


After  the updates are complete, the servers that have core components  installed need a special command to be run. If you didn’t go by the step by step documentation, you may not update the SQL database with this:

Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn yourbackend.FQDN -Verbose

This command will re-install SQL the changes that were dropped by the updates.

Next run get-csmanagementconnection to verify the name of your CMS database  then run  this on the CMS database server:

Install-CsDatabase -CentralManagementDatabase -SqlServerFqdn CMSnameFQDN -SqlInstanceName DBInstanceName-Verbose

When this completes run enable-cscomputer

When this completes – the last step is run from an administrator command window –

“%ProgramFiles%\Microsoft Lync Server 2013\Deployment\Bootstrapper.exe

Of course please see the Instructions from Microsoft to apply CU1 is here – Microsoft TechNet
