Lync 2013 – Removing the Proxy Authentication Prompt at login — Fixed in Septembers Lync Client Update–

Hello All

A while ago I published a post here which helped remove the issue with proxy prompting on the Lync 2013 client login.

Just to recap in Lync 2013 when you logged into the Lync client, it would try a number of ‘http/s’ commands before actually failing back to DNS entries for resolution/redirection. The problem with the Http lookup was it was dependent on your in-house limitations around web proxying and meant that the end user would be required to enter higher privileged username and password to bypass the proxy prompt. As not all users have these kind of creditionals they would continue to be plagued by this issue forever more.

Thankfully, in the latest September 2013 update patch <Which can be found here>, Microsoft have finally corrected this issue and no more would a user have this annoying prompting.

So how have Microsoft managed to do this?? Well simple.. they’ve removed the Http\s lookups from the startup of the lync client and therefore the client simply uses DNS discover and static DNS entries like it used to do in the good old days.

below are my logs PRE and POST upgrade.

Lync 2013 – September 2013 Client Updates

Over the weekend Microsoft re-released the Lync 2013 client update to the world. If you remember this is the patched which was pulled from the shelves last week due to a bug in the software update.

As part of the patch, it comprises of three updates which needs to be run in a particular order.

Prerequisites
To install this Lync 2013 update, make sure that the following updates are installed.

Updates for Office first

MSO (KB2727096)
MSORES (KB2817624)
IDCRL (KB2817626)

and then the actual lync client update http://www.microsoft.com/en-us/download/details.aspx?id=40301

These patches come in both the 32bit and 64bit formats based on your Office client deployment.

You can find details of the downloads here http://support.microsoft.com/kb/2825630. Also you will find the KB articles which relate to the downloads.

NOTE: On installation within my lab I was finding the presence between Outlook and Lync not working as expected. At the time of writing im still evaluating if this is a actual issue. Reports are others are seeing this issue as well.
