A recent update to Mcafee products results in intermediate certificates being installed in the wrong certificate store.

This update and change to the trusted root certification store causes Lync 2013 and Skype for Business Conferencing service to stop responding

Solution:

Removal of the two Intermediate certificates COMODO RSA Code Signing CA and VeriSign Class 3 Code Signing 2010 CA from the Trusted Root Certification Authority store and reboot of the server will solve the issue
