Description* UPDATE - 12:25pm *
The affected server has been rebooted successfully and the errors have been cleared. Sorry for the inconvenience!
While working to get our systems to allow for manual Windows updates (preferred method to help manage downtime for this service), the Lync Front End Server 1 started throwing some alerts. This has not caused any reported problems for users at this time. It will be required to restart the server immediately to resolve the issue. If you are connected to this server, you will be moved to the next available server immediately. The impacted server will be back up within 10-15 minutes and you will be moved back if you were on it before when it is ready to accept new connections.
