July 21, 2016 — KB3172614

• Addressed issue in Host Bus Adapters (HBA) that was including non-Fibre Channel HBA devices in the Fibre Channel HBA list.
• Added support to set the idle timeout value of a TCP connection used by WinHTTP.
• When you try to configure connecting a SCSI storage device to a Windows Hyper-V Host, the Host will not recognize the SCSI storage device when Logical Unit (LUN) 0 is not present.
• When there is more logging session churn on the system because of workloads that are being run, Event Tracking (ETW) will crash.
• Improved reliability of Hyper-V Replica (HVR) by increasing the timeout value and the free disk space threshold. For more info, see KB3184854.
• If you installed the May 2016 update rollup for Windows 8.1 and Windows Server 2012 R2 (KB3156418), the DFSRS.exe process may consume a high percentage of CPU processing power (up to 100 percent). This may cause the DFSR service to become unresponsive and you may be unable to stop the service. You must hard-boot affected computers to restart them.

August 16, 2016 — KB3179574

• Addressed issue that causes the loss of available memory when running queries using the domain name service (DNS).
  Improved performance by addressing an issue that was causing duplicate broadcast data packets to be received by each network interface card (NIC) and sent to applications, when NIC Teaming or Load Balancing/Failover (LBFO) is set-up in active/passive mode.
  
• Addressed issue that sometimes causes backups to fail or servers to hang with drivers that use the IoVolumeDeviceToDosName() routine.
  
• Addressed issue with domain controllers that periodically reboot after a Local Security Authority Subsystem Service (LSASS) module fault, causing the interruption of application and services that are bound to the domain controller at that time.
  
• Addressed issue with DNS servers that get stuck in a loop and stop responding to DNS queries.
  
• Addressed issue with cluster services that stop working when network loss logging occurs. This occurs when a network connection is down and virtual machines (VM) are configured with one possible owner.
  
• Addressed issue in Server Message Block (SMB) server that causes the server to crash intermittently with error 0x50.
  
• Addressed issue that causes domain controllers (DC) to stop working when generating compounded tickets.
