Deploying the Lync 2010 Mobility Service

December 9, 2011 by · 243 Comments 

Now that the Lync 2010 Mobility Service has been out for a week there has been ample time, relatively speaking, to dissect the documentation, run through multiple installation attempts, and perform some initial discovery work on exactly what this new service is and how it appears to function.  Understanding these concepts can greatly increase the […]

Polycom DMA and Lync Integration

August 30, 2011 by · 86 Comments 

The past video conferencing integration articles have primarily discussed the Real-time Media eXperience (RMX) platform, but the  Distributed Media Application (DMA) also supports direct integration with OCS and Lync and is the preferred SIP path when both devices exist in an environment. Out-of-the-box DMA integration instructions are included in the Polycom UC Deployment Guide for […]

Certificate Requests in Windows Server 2008

August 15, 2011 by · 16 Comments 

The primary function of this article is to serve as a reference guide for submitting offline certificate requests against either a private Windows Enterprise Certificate Authority (CA) or various public third-party certificate authorities.  When requesting certificates for servers, applications, or hardware devices most solutions work well when a commonly known certificate template is used to […]

Lync Phone Edition Incompatible with Wildcard Certificates

February 12, 2011 by · 11 Comments 

As discussed in this previous article I am not a big fan of wildcard certificates.  Here is another reason why. Lync Phone Edition devices do not support the use of wildcard entries in certificates on any Lync Server role.  If used on either the Front-End or Access Edge server certificates then the phones may not […]

September 22, 2009 by · Leave a Comment 

There are a pair of related Office Communications Server 2007 topics I wanted to expand on from previous blog articles that I’m still seeing come up quite often in both day-to-day projects and in the Microsoft discussion forums.  One of them is centered around adding and supporting additional SIP domains.  And because the two most […]

OCS Certificate Deployment White Paper

August 28, 2009 by · Leave a Comment 

Microsoft has just released a new white paper on using certificates with Office Communications Server.  Although entitled “OCS 2007 R2 Deploying Certificates” it actually covers both 2007 and 2007 R2 versions of OCS. This is a very comprehensive document (just short of 100 pages) that covers everything from basic requirements down to specific scenarios like […]

OCS R2 CWA Single Certificate Configuration

August 19, 2009 by · Leave a Comment 

Although I find it best practice to deploy two separate certificates on an OCS R2 Communicator Web Access server, there are times when using a single certificate for both server-based MTLS and client-based SSL communications are the best approach, mainly cost if an internal CA is unavailable and all certificates are being purchased.  The problem […]

Managing Certification Authority Certificates for OCS

August 5, 2009 by · Leave a Comment 

Typically in a basic deployment there are times when Windows workstations and servers which are not members of the internal Active Directory domain need to communicate with OCS servers.  This could be attempting to sign-in to Office Communicator installed on a test workstation on the internal corporate network, as well as a perimeter-network server (like […]
