Microsoft Lync audio/video conferencing not working

My Lync 2010 FE server is having problems starting its audio and video conferencing services. It saying it is dependent on the CNG key isolation services.  I have been looking at the forums and it seems it is certificate related in some form.  I removed all the latest patches that were done on the machines. As this took place after a updates were done.  I have looked at the certificates and they seem fine.

This is the error that is thrown when I try to restart.  It seems to be pointing to a certificate issue.


Unexpected error occurred in the LS Audio/Video Authentication service.
