Anatomy of a SIP Domain Change

Overview

Mergers, acquisitions, and branding initiatives usually necessitate a significant but poorly understood change to a Lync Server deployment: a change to the domain name used in the Lync user SIP address (the right-hand-side of the @ sign).

Making this change in a way that minimizes user disruption is a challenge. This blog post aims to provide additional insight and guidance on the user impact, the process to follow, and what changes are required to your infrastructure.

It was written for Lync Server 2010, but all of it should be applicable to Lync Server 2013 (as far as I know).

A Fix for the Lync 2010 Control Panel Crash Issue on VMWare

For those living with the annoying issue of the Lync Server 2010 Control Panel crashing on a VMWare image, a fix has quietly been released in the form of a new update to Silverlight (which was the underlying cause).

The original issue was caused by a Silverlight 5.x update (specifically Silverlight 5.1.10411.0) and the only workaround was to rollback to Silverlight 4.x. This was annoying when updates applied to the image re-upgraded Silverlight to the 5.1 version and the issue surfaced again.

On March 12, 2013 Microsoft released an update to Silverlight 5: see MS13-022: Vulnerability in Silverlight could allow remote code execution.

This updates Silverlight to be 5.1.20125.0 and . . . → Read More: A Fix for the Lync 2010 Control Panel Crash Issue on VMWare

December 2011 Updates for Microsoft Lync Server

In mid-December 2011, Microsoft released an update for Lync Server 2010. This flew under the radar for many people, including myself, because the update is distributed under the same knowledge base article (KB 2493736) and download link as the previous November 2011 CU4 update.

This was done to ensure that a couple of post-CU4 updates made their way into the current Windows Update cycle instead of having to wait until next quarter. Note, this December update shouldn’t be confused with a small re-release of the November CU4 update that happened in early December (a missed standalone MSP was added).

The December 2011 update includes updates to the Front-End, Core Components, . . . → Read More: December 2011 Updates for Microsoft Lync Server

Lync Client and Server Cumulative Update Package (CU4)

Lync Updates Available on Microsoft Update

Several people have inquired about this in the past.

Today, the Microsoft Lync team officially announced that both the Microsoft Lync Client and Server Updates are Available on Microsoft Update. They also acknowledged that this is the first time, which explains why the previous updates, such as January 2011, were not available.

The April updates should be available as of today.
