A question that came via email from an AD admin was about ways to package an MSI file for Lync 2010 client installation via group policy.
It is a common practice to deploy software using group policies and Lync is no exception. But, when you have a look at the downloaded Lync 2010 client, it is an exe and not an msi file. So, how do we go about packaging the Lync client?
Fortunately, Microsoft does provide an MSI, but not in a straightforward fashion. install the Lync 2010 client on a machine and the MSI file is created as part of the install in C:\Program Files (x86)\OCSetup folder. There it is!
Use this msi file to push the Lync 2010 client using group policy. One hurdle that you need to overcome is the fact that msi install of Lync client is not allowed by default. A registry edit takes care of this problem. Read KB2477965 for the fix.
