After three years of using System Center Configuration Manager, we are finally leveraging it to manage the security updates for our server collection and a significant part of that task is to ensure that we research as to whether there are any known issues with the updates that may potentially cause issues with our servers. While browsing online for any problems that may have been documented with the October release of updates, I came across this post from Microsoft regarding three updates to look out for…
Other than that…good luck and Happy Patching!
Security update for Microsoft Exchange Server 2013 and 2016: October 9, 2018
When you try to manually install this security update in “normal mode” (not running the update as an administrator) by double-clicking the update file (.msp), some files are not correctly updated. When this issue occurs, you do not receive an error message or any indication that the security update was not correctly installed. Also, Outlook Web Access (OWA) and the Exchange Control Panel (ECP) may stop working. This issue occurs on servers that are using user account control (UAC). The issue occurs because the security update does not correctly stop certain Exchange-related services.
To avoid this issue, run the security update in elevated mode, as an administrator. To do this, right-click the update file, and then click Run as administrator.
This issue does not occur when you install the update from Microsoft Update.
October 9, 2018—KB4462917 (OS Build 14393.2551) – Windows 10, version 1607; Windows Server 2016
After installing this update, installing Window Server 2019 Key Management Service (KMS) host keys (CSVLK) on Window Server 2016 KMS hosts does not work as expected. Microsoft is working on a resolution and will provide an update in an upcoming release.
October 9, 2018—KB4462923 (Monthly Rollup) – Windows 7 Service Pack 1; Windows Server 2008 R2 Service Pack 1
After you apply this update, the network interface controller may stop working on some client software configurations. This occurs because of an issue related to a missing file, oem<number>.inf. The exact problematic configurations are currently unknown.
 To locate the network device, launch devmgmt.msc. It may appear under Other Devices.
 To automatically rediscover the NIC and install drivers, select Scan for Hardware Changes from the Action menu.
Alternatively, install the drivers for the network device by right-clicking the device and choosing Update. Then choose Search automatically for updated driver software or Browse my computer for driver software.
