Sometimes you get Front End Services to stop unexpectedly and in the event error you receive the message: “The Office Communications Server Front-End service terminated with service-specific error 2147975170 (0x80078002)”.
This is a rare event, but it might occur in scenarios when the Archiving Setting “Shutdown if archiving fails” is enabled or something happens to Archiving Server, such as the service stopping or the server going offline (power failure, hardware failure or another reason).
Keep in mind that disabling options should be our last resort, I mean, if this option is enabled there must be a reason for that. The first step would be trying to figure out what problem occurred in Archiving Server.
In the Event Viewer look for this:
The Office Communications Server Front-End service terminated with service-specific error 2147975170 (0x80078002).

This happens when “Shutdown if archiving fails” is enabled. To solve this we have to fix the Archiving Server or disable the options.
In Office Communicator Server 2007 R2, Microsoft has split Monitoring Settings and Archiving Settings in Pool View and we have now this:
