Description

The Microsoft Lync Server 2010 Protocol Workloads Poster is an update of the Office Communications Server 2007 R2 protocol poster, which was released in 2009 and is still available. So many customers and professionals liked it and found it useful that they requested I update it for Lync Server 2010. Encouraged by the positive feedback, I made it a priority to release an updated poster for Lync Server.

Since the initial release early the week of November 15, 2010, customers and UC professionals sent in e-mails with positive comments and valuable feedback regarding inaccuracies and enhancements. Providing accurate information is important—every effort is made to quickly update the poster so that erroneous information isn’t disseminated.

To help you track the latest update of the poster, you’ll notice a version number in the upper-left corner of the poster.

The current and latest update is marked as version 5.10. This version updates the HTTPS flow from the reverse proxy through the Director to the pool. The Director proxies the web connection to the destination Web pool in the IM and Presence workload. Additionally, details about the Mobility Service and the Autodiscover Service are incorporated as well. These services are a separate MSI download for Lync Server 2010, and can be downloaded here.

As the "guardian" of this poster, I'm committed to keeping the poster updated. You can download the poster from here. Hope you like it!

Purpose

Isn't eye-candy enough to serve as a purpose? You can print it and hang it in your office. Co-workers passing by will immediately be impressed by your technical prowess, and your manager will suddenly, to your surprise, give you a raise. We've heard customer stories reporting unexpected good luck coming their way. So, go ahead and plaster this protocol poster on your wall, and let the goodwill shower down on you.

In addition to good fortune, this poster provides an understanding of the protocols and ports used for each workload. By isolating the protocols for each media, you can gain a better understanding of how Lync Server works. This deeper understanding can help you troubleshoot problems with a specific media in your Lync Server deployment.

Because certificate configuration can be confusing, this poster also details which settings to define in the server certificate request. If you don't find these settings defined in the certificate issued, it is an indication that the server certificate wasn't properly requested from the certification authority (CA).

Domain Name System (DNS) is a configuration step that can often be missed and is prone to misconfiguration, particularly for Edge servers. The poster lists the DNS configurations that are needed for Lync Server.

Last, but not least, this poster has useful links to where you can obtain additional resources, such as articles, the Microsoft Office Communications Server 2007 R2 Resource Kit book, product documentation, and useful tools. You'll notice a Microsoft Tag. Take a picture with your mobile phone, and the picture will automatically resolve the embedded URL to NextHop. Here you'll find lots of useful technical articles and a community of like-minded technical professionals, such as yourself. The Microsoft Tag application must be installed on your phone.

Summary
