KB974571 Crypto-API Update may break Office Communications Server 2007 R2 installations条评论
Security updates are important. And as we’re currently an evaluation setup for OCS 2007 R2, i’ve decided to install todays batch of security updates on these lesser important machines first. And after a reboot, OCS 2007 R2 Front End Service is not running anymore.
Below are error message from event log:
