Renewing Lync Server 2010/2013 Certificates

One common thing that is asked by customers is: “How do I renew Lync Server Certificates?” If not asked, then sometimes we get a customer with certificate issues or even with Lync services off because of an error in certificates creation/renew (or even people that forget to renew the certificate). So, moving on, we decided… Read more

Lync Server 2013 Cumulative Update List: July 2017

Since we already have a Lync Server 2010 Cumulative Update List it makes sense to have the same for Lync Server 2013. We can use the Cmdlets described in Lync Server Component Version to know which version is installed.

Configuring ARR for Lync Server

Sometime ago we got into a situation where a customer deployed ARR as a Reverse Proxy for Lync Server. This was new to us.

EnableFastFailoverTimer in Lync 2013 Trunk Configuration

New stuff has been added to Lync 2013 but some things aren’t visible right away. On the Lync administrator side the interface didn’t change much – Control Panel and Topology are almost the same, and PowerShell is still black. “Under the hood”, we will find out that things are quite different – new settings, new roles… Read more
