Lync Server 2013 Front End service does not start on pool failback

Symptoms
When you perform a Lync Server 2013 or Skype for Business Server 2015 pool failback, the Front End service (rtcsrv.exe) does not start on one or more Front End (FE) servers. Additionally, Event ID 12314 and 1299 may be logged in the Lync Server event log, as follows:

Time: 9/27/2015 1:02:49 AMID: 12314Level: ErrorSource: LS ServerMachine: ServerName.contoso.comMessage: Unable to create and initialize the stop event, error code is:0x80070005 (Access is denied). The service has to stop.Resolution:This can happen when the server or one of its applications has failed to shutdown. Ensure server and all instances of its applications are stopped and restart the server.Time: 9/27/2015 1:02:49 AMID: 12299Level: ErrorSource: LS ServerMachine: ServerName.contoso.comMessage: The service is shutting down due to an internal error.Error Code: 80070005!_HRX! (Access is denied. !_HRM)Cause: Check the previous entries in the event log for the failure reason.Resolution: Check the previous event log entries and resolve them. Restart the server. If the problem persists contact Product Support Services.
Cause
This problem can occur if the ABServer.exe process is performing its scheduled maintenance during pool failback.
Resolution
To resolve this problem, reboot the FE servers that generate the event ID 12314 log entry.
Workaround
To work around this problem, follow these steps:

  • Run the failover and failback between the ABServer sync intervals.
  • Before you run the pool failback, start services in the target pool (Start-CsWindowsService) and let the AB server complete the synchronization process. Then, search for the following events in the Lync Server event log:

    Front End Service is starting (Event ID: 12287)
    Address Book Service is starting (Event ID: 21001)
    Address Book Service is started (Event ID: 21002)
    Address Book Sync pass started (Event ID: 21005)
    Address Book Sync pass in progress (Event ID: 21052)
    Address Book Sync pass Summary (Event ID: 21056)
More information
During the pool failback, the Front End service (RtcSrv.exe) has to be started. If the Address Book synchronization is still running, this prevents the RtcSrv.exe process from starting. If the Address Book process takes more than 60 minutes to complete, the Front End service fails to start and causes the problem that is described in the "Symptoms" section.
Status
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
