Nice post by Rune Stoknes on a recently discovered faulty patch from Microsoft on the Lync server.
This post proves why you should never rely on Windows Update to install your Lync patches. Always use the LyncServerUpdateInstaller that comes with the CU released for Lync/Skype4B.
Keeping your servers up to date is essential, and not only the application server parts but the OS and others as well. The other day I went with a Windows Update that also included a Lync Server security update. After a short while I would get feedback from users no longer being able to use the mobile client, and later I also got reports on the Web App not working.
