Microsoft confirmed some issues with security updates from July 10, 2018 within this blog post (dated August 3, 2018). Some Windows clusters may have issues due to the following updates:
|Operating System||Impacted update|
|Windows Server 2016||KB4338814|
|Windows Server 2012R2||KB4338824, KB 338815|
Application crashes occur when they open HTTP or TCP connections, access can be denied, and more (see blog post for details).
For clusters running Windows Server 2016, installing the latest version of the updates should mitigate the problem. If the Patch Orchestration Application (POA) is running in the cluster, it may already have updated the cluster's machines. Please make sure that the updates mentioned above has been updated..
For clusters running Windows Server 2012R2, there is an additional upgrade to the version released in July as Fix. If the cluster nodes were not updated before July 10, you may need to apply the July 10 update first, and then run the Windows update again to fix the problem. Details can be found in the blog post of August 3, 2018.
